Hello all. I need your help in imposing a constraint to a structural simulation in ANSYS MAPDL. <\/p>\n

This model uses temperature results generated from a different (thermal) model as input, and the results so far are promising. However, I need to impose a boundary condition whereby when a certain temperature is reached, instantaneous annealing and creep occur. In other words, the stress and all components of strain (plastic, thermal, etc.) on an element need to be reset to zero when the temperatures at all Gauss points of this element exceed a certain value (Trelax). <\/p>\n

Can you please assist me in imposing this condition? I cannot seem to find a way to impose values to stress and strain, as they are usually output values that are not directly controlled by the programmer. Thank you for your time.<\/p>\n","protected":false},"template":"","class_list":["post-163810","topic","type-topic","status-closed","hentry","topic-tag-apdl","topic-tag-creep","topic-tag-structural","topic-tag-thermal-structural-1"],"aioseo_notices":[],"aioseo_head":"\n\t\t\n\t\n\t\n\t\n\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t
