Abstract

The infrared stress analysis technique has been used to evaluate the stress concentration factors for several kinds of notches in the sheet specimens and in the cross shaped specimens, and to estimate the stress intensity factors for CT specimens. The results were compared with independent numerical and theoretical results. The stress concentration and stress intensity factors determined by the infrared technique tended to be slightly lower than those of other comparable independent values. 1 Introduction The local stresses and strains near notches and cracks are very important for fracture analysis of cyclically loaded structural components. A number of experimental techniques such as photoelasticity and numerical methods such as finite element analysis have
