An integrated strategy for variational analysis of compliant plastic assemblies on shell elements
Full text linkResistance spot welding process simulation for variational analysis on compliant assemblies
No full textThis work proposes a methodology that can be used to define a FEM simulation of the body welding process with the aim of evaluating compliant assembly deformations and spring-back, considering the effect of material plasticity, in order to improve the results of variational analysis methods, which so far have been based on a linear elastic material model. With reference to the automotive field, the simulation considers the effects of fixturing and resistance spot welding applied to sheet metal parts subjected to dimensional and geometrical tolerance
Compliant assembly tolerance analysis: guidelines to formalize the resistance spot welding plasticity effects
Full text linkComputer Aided Morphological Analysis for maxillo-facial diagnostic: a preliminary study
Full text linkThis article compares most of the three-dimensional (3D) morphometric methods currently proposed by the technical literature to evaluate their morphological informative value, while applying them to a case study of five patients affected by the malocclusion pathology. The compared methods are: conventional cephalometric analysis (CCA), generalised Procrustes superimposition (GPS) with principal-components analysis (PCA), thin-plate spline analysis (TPS), multisectional spline (MS) and clearance vector mapping (CVM). The results show that MS provides more reliable and useful diagnostic informatio
A methodology for supporting the design of a learning outcomes-based formative assessment: the engineering drawing case study
No full textThis paper presents a learning outcomes-based methodology to produce a summative assessment to use in any course at any educational level. It takes into consideration the European Qualifications Framework (EQF) to define the learning outcomes, Bloom’s taxonomy to define the assessment questions and the QR code to help managing large class size. The methodology has been applied in a case study regarding the technical drawing course of the BSc Engineering programme at the Faculty of Engineering in Italy. In general, the implementation of the new assessment, during the two academic years of analysis, has shown good results in terms of reduction of failures (7% in the first year and 3.9% in the second year), improvement of the weighted average mark (4.6%), reduction of the minimum mark obtained (8.1%), increase of the maximum mark obtained (3.1%) and time reduction of 48% to upload marks to the electronic register
