Hi,

I am trying to model frequency dependent thermal strain system with the form e_th(w) = a*(T(w)-T_ref) (e_th : thermal strain , frequency dependent T(w) : induced tempereture, frequency dependent a : coefficient of thermal expansion)

Could you please give me an advise how to start? Is it right to only using solid mechanics or do I have to use Multiphysics(Thermal Stress?)

Hi, Eunyoung

You needs make frequency dependent functions for T(w) and a.

Assuming that there is no temperature distribution for the entire geometry, only Solid Mechanics can be used, but if a temperature distribution is required, Heat Transfer for Solid and Thermal Stress must be used together.

Best regards, Jonghyun Yi
