hello

i am new user for simlab 2019.2 . And now i want to simulate a nonlinear problem that about 2 combine plate with a thermal load by time varied. For example, all simulated body heated from 300K to 400K in 20s. 

 

I want to analysis the stress and strain by time varied.

Can i got some tip or material ?

THANKS!

    Can you share what kind of nonlinear you want to simulate(Contact, Material, large strain)?

    HELLO

    THANK for your reply.

     

    My study is the reliability of electronic plate analysis. I want to simulate the object heated and cooled (thermal cycle test), then got the stress and strain.

    The temperature condition like this,  and my model is just a simple PCB (3 piece combined)

    How is the problem solver by using SIMLAB ?

    THANKS

    I study some paper like simulation the thermal cycle, another paper analysis the results

    how can i do this job in simlab? 

    THANKS
