Optimal strain gage locations for experimental determination of stress intensity factors

Abstract

Stress intensity factor SIF is an important parameter in linear elastic fracture mechanics as its limiting value decides whether an existing crack in a component grows or not Use of linear elastic fracture mechanics principles in predicting and preventing fracture of engineering components largely depends on the availability of accurate values of SIF Among all the experimental techniques strain gage techniques are relatively inexpensive simple and easy to use for the determination of the S
