Stress History Simulation. Volume 2. A User's Manual for a Computer Program to Modify Stress History Simulations

Abstract

This report presents a description of a computer program to combine and modify stress history simulations generated by a companion computer program described in Volume I. Input random stress history data sets are combined and modified to create stress spectra variations. Each variation is characterized by its mission mix; a mission mix consists of a particular order of mission types (Air-to-Air, Air-to-Ground, and Instrumentation and Navigation). An example problem is included which demonstrates the program output; a sequential list of peaks and valleys of the flight by flight spectrum, and a summary table of the coupling of the peaks and valleys. Both of the computer programs were used in a study of load sequence effects on crack growth, summarized in AFFDL-TR-76-112, 'Effects of Fighter Attack Spectrum on Crack Growth'.
