RM sigma effective and swelling issue.
The following discussion from !3247 (merged) should be addressed:
After this line, can you please add
_ip_data[ip].sigma_eff += sigma_sw, and remove
_ip_data[ip].sigma_eff + sigma_swin the other parts of this function? The same change could be applied to
The effective stress includes the contribution from the swelling. With the current implementation, the stress integration excludes the port of effective stress by the swelling.
