Hi, I have been using *Initial Conditions, type=STRESS to import stresses. It worked well for C3D8R solid elements. However, I struggled to get it work for continuum shell elements SC8R.
I performed identical CAE operations but when using SC8R, the initial stresses imported were always zero. This is bizarre. Does it mean that *Initial Conditions, type=STRESS does not support continuum shell elements?
Shiyao Lin as per my understanding, shell elements primarily capture in-plane stresses (membrane behavior) and bending moments. Initial stress definitions in ABAQUS are typically for normal and shear stresses. Directly applying these to shells might not translate well to the bending behavior that shells are often designed for. I am not sure, let's wait for the expert reviews further.
I used initial stress definition to solve this problem, meaning that I define stresses element by element in my input file.
