Base di statua da Rodi con citazione di Aristofane
No full textThe statue base, found in Rhodes and belonging to the second/first century BC, preserves verses 454-9 of Aristophanes’ Frogs headed by the name of the author in the genitive: it is the only known epigraphic example of a classical text introduced by its author’s name. The inscribed text is also significant for the textual tradition of the Frogs, since it confirms the reading of some ancient medieval manuscripts. The inscription was found near the ancient gymnasium, where a library has recently been identified: it suggests that the text belonged to an educational context. At the same time, the religious aspect is evident both in the inscribed verses and in the comparison with a dedication from the Rhodian Peraea made by gymnasiarchs to Helios. Hence, the inscription contributes to our knowledge of the cultural, educational and religious environment of the late Hellenistic age Rhodes

Algoritma Rapidly Exploring Random Tree Star Dengan Integrasi Metode Sampling Goal Biassing, Gaussian, Dan Boundary
No full textThe path planning algorithm is to find a path that takes the robot from the start state to the goal state while avoiding collisions with obstacles. In path planning, various applications have been used such as animation, medicine, aircraft, etc. The purpose of this study is to design a new sampling method by integrating sampling methods based on goal biasing, Gaussian and Boundary and then implementing it in path planning problems using the Rapidly Exploring Random Tree* (RRT*) algorithm. We call this sampling method the integration sampling method. The path planning algorithm using this integration sampling method is implemented in the Labview programming language. The algorithm parameters in Labview can be modified to observe the output performance of the RRT* algorithm. The test was carried out in an environment of obstacle clutter, SquareField BW, and traps, where the test was carried out 20 times for each obstacle. The test was conducted to compare the path distance and computation time of the RRT* algorithm using the integration sampling method, against the RRT* algorithm using the Gaussian, and Boundary sampling method. Based on the test results, it is found that the RRT* algorithm using the integration sampling method can produce a shorter path than the RRT* algorithm using the Gaussian method and the RRT* algorithm using Boundary sampling. Comparison of the resulting computational time is faster than the Gaussian integration method. However, a comparison with Boundary shows that Boundary requires less time than integration. Therefore, it can be concluded that the Rapidly Exploring Random Tree* algorithm integration method is superior to the Gaussian method and the Boundary method.Algoritma perencanaan jalur adalah untuk menemukan lintasan yang membawa robot dari keadaan awal (start) ke keadaan tujuan (goal) sambil menghindari tabrakan dengan rintangan.

Parameter algoritma pada Labview dapat dimodifikasi untuk mengamati performansi output dari algoritma RRT*. Pengujian dilakukan pada lingkungan obstacle clutter, SquareField BW, dan trap, dimana pengujian dilakukan 20 kali percobaan pada masing-masing obstacle. Pengujian dilakukan untuk membandingan jarak jalur serta waktu komputasi dari algoritma RRT* yang menggunakan metode sampling integrasi, terhadap algoritma RRT* yang menggunakan metode sampling Gaussian, dan Boundary. Berdasarkan hasil pengujian, diperoleh bahwa algoritma RRT* yang menggunakan metode sampling integrasi dapat menghasilkan jalur yang lebih pendek dibandingkan dengan algoritma RRT* yang menggunakan metode Gaussian maupun algoritma RRT* yang menggunakan sampling Boundary. Perbandingan waktu komputasi yang dihasilkan lebih cepat metode integrasi dibandingkan dengan Gaussian. Akan tetapi, pada perbandingan dengan Boundary menunjukkan bahwa Boundary memerlukan lebih sedikit waktu dibandingkan dengan integrasi. Maka dari itu dapat disimpulkan bahwa algortima Rapidly Exploring Random Tree* metode integrasi lebih unggul dibandingkan dengan metode Gaussian maupun metode Boundary

The Residual Strength Failure Sequence in Fibre Metal Laminates
No full textThe concept of damage tolerance is a key aspect in ensuring and maintaining safety of an airframe structure over its design life. Developments in materials and structural design have both contributed to improvements in the damage tolerance of modern aircraft structures. Indeed, new developments in metal alloys, composite materials, and hybrid materials such as the Fibre Metal Laminates (FMLs) have all resulted in structures less sensitive to damage and capable to withstand more severe loading conditions. Among other materials, FMLs represent a clear example of damage tolerant hybrid materials, made by bonding thin metal sheets together with fibres embedded in epoxy. Exploiting the damage tolerance capability of FMLs is strictly related to the ability to firstly understand the occurring failure mechanisms, and secondly to be able to accurately describe those mechanisms. In this light, the present dissertation describes the investigation on the residual strength failure sequence in FMLs, and presents the development of an accurate analytical prediction method. The failure sequence is studied in particular for standard Glare laminates, which are relevant laminates for applications in aircraft pressurized fuselages. The developed analytical method has been implemented into two numerical models, considering both through-the-thickness crack and fatigue crack configurations. The developed models are validated against a large number of experimental data, which are also presented in this thesis. The main concept in this dissertation is that the crack growth process in the metallic layers of an FML can be described with the Crack Tip Opening Angle concept (CTOA). This approach includes the contribution of the fibre layers (e.g. fibre failure and fibre bridging) and the associated quasi-static delamination growth. An introduction to FMLs and to all various Glare grades, lay-ups, and manufacturing processes is provided in chapter 2. Some current and future applications for aircraft structures are also discussed in that chapter. A qualitative description of the principal failure mechanisms occurring during the residual strength failure sequence is presented in chapter 3. Based on experimental observations, the metal crack growth mechanisms, permanent plastic deformation, fibre failure and static delamination growth are discussed. All these mechanisms are related to each other, and all contribute to the residual strength of the laminate. The development of the prediction models aimed to be a step forward with respect to previous relevant prediction models available in literature. Therefore, both empirical and analytical prediction models available in literature are presented and discussed in chapter 4. A critical evaluation of those models has pointed out their limitations in applicability and versatility towards a “generic FML” concept. From this chapter, some guidelines have been defined to address the subsequent model development. Two types of experimental activities were carried out. The first type consisted in experiments to gain understanding of the deformation behaviour of both metallic and fibre layers. Extensive use of Digital Image Correlation technique enabled to observe and measure the deformation field of both metal and fibre layers, and their interaction. Further insight into the fibre bridging mechanism and into the metal-fibre interaction was obtained. These experimental activities are discussed in chapter 5. The second type of experimental activities aimed to generate input data for the prediction model, and to validate the CTOA approach. These are discussed in chapter 6. A large amount of experimental CTOA tests were conducted on several FML grades to evaluate the CTOA as failure criterion for FML. This included the investigation of the effect of metal sheet thickness, crack length-to-panel width ratio and the effect of bridging fibres. Static delamination growth tests were conducted to obtain the critical Strain Energy Release Rate. This parameter was subsequently used as input in the prediction model to define the critical condition for the delamination growth. Furthermore, in the same chapter, it is also discussed the complex interaction between static delamination growth and plastic deformation of the metallic layers. The core aspect of the present thesis concerns the modelling of the residual strength failure sequence, which is presented in chapter 7. Two models are described: one for the through-the-thickness crack and one for the fatigue crack. Both models are based on the same method, which uses the CTOA as crack growth driving parameter. The method is based on the idea that crack extension in the metallic layers occurs when the calculated CTOA reaches the critical value obtained from CTOA experiments on metal laminates containing the same metal layers used in the FML. The calculated CTOA is a function of the contribution due to the far-field stress in the aluminium layers, and the contribution of the fibres. The fibre can contribute either in terms of crack opening contribution (broken fibres) or crack closing contribution (bridging fibres present in the fatigue crack configuration). Plastic deformation ahead and behind the metal crack tip is accounted and implemented into the calculation. In addition, in the case of fatigue crack configurations, the bridging stress is calculated by solving the deformation compatibility equation, accounting for the plastic zone ahead of the crack tip and fibre failure in the bridging area. The bridging stress is subsequently used to calculate the quasi-static delamination growth occurring at the fibre-metal interface using the Strain Energy Release Rate approach. The model for through-the-thickness crack showed a very good agreement with the experimental data, while the model for fatigue crack configuration showed sufficient agreement with experimental data. The modelling of the fatigue crack configuration presents higher degree of complexity, which required a number of simplifications and assumptions, making the model less robust than the one for through-the-thickness crack. Chapter 8 summarises the conclusions of the investigations. It can be concluded that with the proposed models, the mechanisms related to the residual strength failure sequence are fully described and characterized. The model for through-the-thickness crack is robust and validated, and can be extended to other material and geometrical configurations. The model for fatigue crack is not robust enough, but further improvements are possible.Mechanics, Aerospace Structures & MaterialsAerospace Engineerin
