WebDec 7, 2010 · Hill 1948 Yield Criterion. Many of you, I am sure, use Von Mises as a yield criterion to calculate the equivalent stress and strain on your system. I am using Hill 1948 as it provides an anisotropic analysis. However, I am having trouble calibrating Hill48 using the r-values. where r0 is the rolling angle direction and r90 the transverse direction. WebHill yield criterion was commonly used in the numerical model of wood due to its orthotropic characteristics [27], [28], [29]. Although the softening behavior of LVL and glubam was simulated to some extent by Hill yield criterion, no crack propagation was considered in this criterion.

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 ...
