I need to write a VUEXPAN that link thermal expansion with stress. In each step, the thermal expansion increment 'StrainTherDT' change, do I need to update the corresponding energy? Can anyone share some VUEXPAN subroutine for references. Thanks!
I used ANSYS explicit to solve a deformation problem, the set step time is 1s. I added a displacement boundary condition that linearly increased with time. But the total time in the solution is...

I added prestress in my inp file, and this error occurs. And when I comment that line, this error disappears.

Does they effect the stress distribution? From my understanding, the only fundamental difference between CPS4R and CPE4R is their 'k' is different, which is similar to materials with different...

The prestress is much larger than its elastic stress limit, which means if I add this stress to the material, the material will endure plastic strain immediately. Should I only input the elastic...

I want to model a metal with initial plastic strains and stress (stress > yield stress). Stress can be added with prestress. So how to add PEEQ? Or I don't need to add PEEQ, Abaqus will calculate...

Hi all, I want to adding prestress under cylindrical coordinate as a function of R and sita, can Abaqus do that? For example, how to add constant radial pressure as prestress to a ring in Abaqus?

The monitor shows I have calculated 29 steps, but I can only see 7 steps from the results though the visualization. I use the abaqus 2018 explicit solver. Thank you
