Description: Both history output and field output of MISES (PSD of Mises stress) and RMISES (RMS of Mises stress) can be requested. Abaqus/Standard writes the needed generalized response data to the output database (.odb) file. Abaqus/Viewer accesses these data and computes the PSD and RMS stresses using the method outlined in Sandia National Lab report  SAND98-0260, “An Efficient Method for Calculating RMS von Mises Stress in a Random Vibration Environment,” by Segalman, D. J., et al. Both contour and X–Y plots can be obtained.
