Progress Report on Aircraft Fatigue Studies.
Abstract
This report summarizes a year of research activity on aircraft fatigue in three areas: (1) The influence of minimum load levels, ground loads, order of loading and counting method on the damage calculation, (2) The method of calculating local stress in the plastic range at the stress concentration site from the recorded in-flight strain monitor and (3) The measurement of relaxation of residual stresses after they are produced locally at the point of stress concentration. Substantial progress was made in all three areas and especially the first two. (Author)
