    ANSYS plasticity law implementation

    Have you ever implement a plasticity law in ANSYS like the Ramberg-Osgood one? USERMAT are so awful... Could you help me? Thanks

    Residual stress and piezoelectric material

    Hi, How can I take into account the residual stress of a piezoelectric material in a piezoelectric analysis? PLANE13/PLANE223 do not accept INISTATE command to do so... Best regards

    RVE and homogenization technique

    Hello everybody, For the purpose of describing macroscopic thermo-mechanical behavior of BEOL (Back End Of the Line) interconnect structure, the heterogeneous BEOL stack (Cu, porous materials...) may be approximated as a homogeneous medium with certain effective moduli and Poisson ratios. I'm...

    How to take in account the CTE of a resin in electronic package?

    Hi, I would like to know how to enter the evolution of the CTE of a resin vs. the temperature because a resin has got a glass transition temperature so there are 2 CTEs... Thankd in advance.

    ANSYS - Creep Problem

    Dear community, I'm trying to simulate a creep test done with the 3-point bending method (DMA test) under ANSYS to compare reality to ANSYS results. The material used is a PbSbSn or a PbSnAg soft solder following the Garofalo model (CREEP option in ANSYS with PLANE182) but the strain resulting...
