Evaluation of Stress Intensity Factors in Precracked Open and Riveted Holes Using the Methods of Caustics,

Abstract

The method of 'caustics' is investigated and analyzed as a means of evaluating stress intensity factors, K sub I, in cracks radially emanating from holes drilled in aluminum and steel specimens. The results from cracks in open holes in specimens under uniaxial tension loads, are compared with results obtained analytically. Effects of compressive residual stresses in reducing K sub I are demonstrated. (Author)
