energy density associated with yielding is 1 2 dY3 U E (0.14) Thus, the energy density given in Eq. (0.14) is the critical value of the distortional energy density for the material. Then according to von Mises’s failure criterion, the material under multi-axial loading will yield when the distortional energy is equal to or greater

peaked at a particular value of x, and the probability density, being its square, is likewise peaked there as well. This is the wavefunction for a particle well localized at a position given by the center of the peak, as the probability density is high there, and the width of the peak is small, so the uncertainty in the position is very small.
