Hill yield criterion
WebIn ABAQUS/Explicit anisotropic yield can be used in conjunction with the models of progressive damage and failure discussed in “Damage and failure for ductile metals: overview,” Section 19.2.1.The capability allows for the specification of one or more damage initiation criteria, including ductile, shear, forming limit diagram (FLD), forming limit stress … 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.
