Title: An efficient method for calculating RMS von Mises stress in a random vibration environment

An efficient method for calculating RMS von Mises stress in a random vibration environment An efficient method is presented for calculation of RMS von Mises stresses from stress component transfer functions and the Fourier representation of random input forces. An efficient implementation of the method calculates the RMS stresses directly from the linear stress and displacement modes. The key relation presented is one suggested in past literature, but does not appear to have been previously exploited in this manner.
