Isotropic power law hardening material model.

Before yield, the stress is youngs modulus * strain. After yielding, the stress is K* pow(strain, n) where K is the strength coefficient, n is the strain hardening exponent and strain is the total strain. Yield stress is the point of intersection of these two curves.
