This simulation is of course realizable, acyually, recently I've done such a work. The residual stress within a duplex coating has been investigated.

If the plasticity is to be considered, a ‘transient’ analysis should be carried through to involve the loading history effect on this problem, during which the inertia effect can be neglected in the analysis.

thermal stress in ANSYS

Hallo,

I'm using ANSYS for study the internal stresses of a trilayer structure resulting after a cooling process. The middle layer (the solder) has temperature dependent material properties and the other two layers can be considered temperature indipendent mat. properties. If I use a static analysis the software uses the material properties reffered to final temperature.

For an linear elastic analysis is this a realistic procedure?

If the solder deforms plastically at high temperature and not at final temperature..how can I do?

I try to do a transient analysis defining the properties of solder at various temperatures. The tensile stress resulting in solder layer is very close to the one from static analysis.

Thanks...
