MULTI FRACTURE/DELAMINATION ANALYSIS OF COMPOSITES SUBJECTED TO IMPACT LOADINGS

A combined finite/ discrete element method is presented for modelling of composite specimens subjected to dynamic/impact loadings. The main task is set on developing an algorithm for simulation of potential bonding and debonding/delamination phenomena during impact or general dynamic loading conditions. In addition, full fracture analysis can also be performed. The proposed approach adopts a ge...

Virtual Trauma of Petrous bone fracture under lateral impact : from medical images to fracture process evaluation

Materials and methods A CT-Scan of a volunteer without pathology in relation with the Petrous bone was used to build a numerical model. Using Scan2Mesh [6], a tool dedicated to the generation of a mesh from medical data, 169 slices separated by a thickness of 0.6 millimeters were processed, using an automatic detection method based on thresholding. Then an anatomist checked the detected contour...

Failure Behavior of Unidirectional Composites under Compression Loading: Effect of Fiber Waviness

The key objective of this work is to highlight the effect of manufacturing-induced fiber waviness defects on the compressive failure of glass fiber-reinforced unidirectional specimens. For this purpose, in-plane, through-thickness waviness defects (with different waviness severities) are induced during the manufacturing of the laminate. Numerical and experimental results show that the compressi...
