Stress History Simulation. Volume I. A User's Manual for a Computer Program to Generate Stress History Simulations.

摘要

This report presents a description of a computer program to generate stress histories using random noise theory. A Gaussian random time history is generated and searched to detect peaks and valleys. The Gaussian peak and valley history is transformed to simulate real time history. The resulting list of peaks and valleys is filtered, using input rise and fall criteria, in order to eliminate stress excursions that the user does not wish to consider.
