WebApr 23, 2024 · Equation related to stresses may be written as follows: (1) where ε ela is the elastic strain, ε pl is the plastic strain and ε th is the thermal strain. Available strain measures are described in Stress-Strain measures and thermal strains computation is described in Thermal loads. The stress field must satisfy a criterion (stresses must be ...
