Strain gage based determination of stress intensity factors in cracked orthotropic materials

Abstract

In the last few decades considerable attentions have been paid by researchers in extending the concepts of LEFM pertaining to homogenous isotropic materials to orthotropic composite materials Stress intensity factor SIF being an important parameter in LEFM accurate determination of SIF of cracked orthotropic materials have been an important area of research Existence of cracks and notches in laminated composites warrants that SIFs are known to assess whether such cracks grow further during
