The second criteria is a triaxiality dependent plastic strain based failure criteria applied the matrix phase level. Improved failure predictions using a triaxiality failure model applied at the composites level were demonstrated using an uncoupled Digimat® with Abaqus approach [6].
Artificial intelligence assisted fatigue failure prediction
Web27 de jul. de 2024 · The strain-based forming limit curve is the traditional tool to assess the formability of metal sheets. However, its application should be restricted to proportional loading processes under uniform strain conditions. Several works have focused on overcoming this limitation to characterize the safe process windows in industrial stretch … Web20 de ago. de 2024 · Fatigue life prediction of materials and structural details can be modeled by deterministic and probabilistic analyses. Fatigue damage in metals generally initiates near the surface and spreads perpendicularly to the loading direction; this behavior is linked to cyclic plasticity and isotropic mechanical properties. dynamic lowenstein cognitive assessment
