I am coding Abaqus UEL for fully coupled temperature displacement analysis. I need help in understanding thermal contribution which adds up to RHS.
I am coding UEL for 3D 8 node brick element with linear isotropic material behavior.
1. Do I have to calculate total stress considering thermal strain and then B'*Sigma will be my RHS?
2. Or do my RHS will be B'*Sigma(elastic) + Thermal Contribution (need to know)
Another query I have is when I check LFLAGS, it is LFLAGS(3) = 4 which means AMATRX will be mass matrix, but I want to neglect inertia effects. So how to define AMATRX in my case, also on what parameters these LFLAGS depends and varies.
Could someone help me through this?
