A stochastic multiaxial fatigue model for off-axis cracking in FRP laminates
Get PDFA model to predict off-axis crack evolution in multidirectional laminates subjected to multiaxial loading is proposed. The model applies multi-scale stress and local fracture mechanics analyses to distinguish between two microscopic damage mechanisms, which govern the damage evolution, as well as determining the magnitude of the damage evolution rate associated with each microscopic damage mechanism. The multi-scale analysis is based on the GLOB-LOC off-axis crack damage model, which is extended to include substantial new capabilities such as the influence of crack face sliding interaction and prediction of variations in the stress field due to the local crack density. The extension of the GLOB-LOC model introduces physically based multiaxial fatigue criteria for off-axis crack initiation and mixed-mode off-axis crack propagation. The extended GLOB-LOC model is implemented and it is demonstrated that good predictions are obtained for the damage evolution under various multiaxial stress conditions. Furthermore it is shown that the model only requires input from two different multiaxial stress states to obtain the material parameters for a given FRP ply.</p
Particles that fight cancer: the use of protons and carbon ions in cancer therapy

Cancer is a major societal issue. A key challenge for cancer therapy is the complex and multifaceted nature of the disease, which calls for personalised treatment. Radiotherapy has been used to treat tumours for more than a century, and is still a staple in oncology: today, 50 % of cancer patients receive radiotherapy, half of them with curative intent.
Hadrontherapy is one of the most technologically advanced methods of delivering radiation dose to the tumour while protecting surrounding healthy tissues. In addition, hadrontherapy can reach otherwise difficult to access deep-seated tumours and can be used for radio resistant tumours as in hypoxia.
This year marks 60 years since the first patient was treated with protons in the US and 20 years since the use of carbon ions in Japan. Join us in learning about the journey of particle therapy in Japan and Europe, its challenges, clinical results and future prospects.

Design, Testing and Simulation of GFRP Cruciform Test Specimen in Biaxial Fatigue
No full textThis project contains design, testing and simulation of a GFRP cruciform specimen subjected to biaxial fatigue. A study of state-of-the-art literature is conducted, where previous designs of cruciform specimens subjected to biaxial fatigue are studied. A specimen geometry and lay-up optimization is conducted in MATLAB which interacts with a solid FE model in ANSYS, wherein a gauge zone is embedded into the specimen with a predefined lay-up, specified by Siemens Wind Power A/S. Designed specimens are tested in biaxial fatigue at different stress levels until failure occurs in the gauge zone. Video camera, DIC and strain gauges are utilized to monitor failure during the fatigue tests. A state-of-the-art fatigue life prediction algorithm, called FADAS, is implemented into an ANSYS programmable subroutine. The algorithm involves a progressive strength degradation, Puck’s failure criteria and a stiffness degradation in order to estimate fatigue life of FRP. FADAS is utilized on an FE shell model of the designed specimen. Simulations of the fatigue test are conducted in order to verify if the FADAS algorithm can predict the fatigue life of these. It is concluded that this version of the implemented FADAS algorithm can not estimate fatigue life within an acceptable tolerance
