Stress in Sensitivity-Based Shape Optimization

The stress in a sensitivity-based shape optimization SIG_MISES is the elemental centroidal von Mises stress, and its sensitivities are approximated using the P-mean Norm.

Formula

SIG_MISES

The σvMises is the elemental centroidal von Mises stress evaluated over the elements in the DRESP definition. While the design response is the true maximum, the sensitivities are approximated using the P-mean Norm. GROUP_OPER = MAX must be used, other GROUP_OPER settings are not allowed.
