Cryer's problem is a three-dimensional consolidation benchmark. A porous sphere is subjected to a uniform boundary pressure. The pore pressure at the center of the sphere rises due to the Mandel-Cryer effect that is captured by a two-way coupling between Darcy's law and solid mechanics. En savoir plus
This model shows how to model a simple Shockley diode— a four-layer PNPN semiconductor device. The Shockley diode is also named as thyristor. In this model, the Analytic Doping Model node is utilized to define the doping profiles for each domain. A time-dependent study is employed to ... En savoir plus
Shape optimization with respect to fatigue properties is not supported, but fatigue properties are well correlated with the maximum stress. The model demonstrates how optimization with respect to a p-norm of the von Mises stress can be used to improve fatigue properties without ... En savoir plus
