calculates and returns the von Mises p-norm functional for all the elements that this object currently stores data for.

This is defined as

virtual

calculates and returns the derivative of von Mises p-norm functional wrt state vector for the specified element.

This assumes that the von_Mises_p_norm_functional_for_all_elems() has been called to calculate the primal data. This is defined as

$\frac{ \frac{1}{p} \left( \int_\Omega (\sigma_{VM}(\Omega))^p ~ d\Omega \right)^{\frac{1}{p}-1}}{\left( \int_\Omega ~ d\Omega \right)^{\frac{1}{p}}} \int_\Omega p (\sigma_{VM}(\Omega))^{p-1} \frac{d \sigma_{VM}(\Omega)}{dX} ~ d\Omega$
