Abstract
This study evaluated notch H-integrals as well as stress intensity factors (SIFs) using image-correlation experiments for anisotropic materials. First, complex displacement and stress functions are deduced into an H-integral equation. Displacements and stresses from image-correlation experiments are then substituted into the H-integral equation to evaluate the notch SIFs. Experimental results compared with finite element analyses show that the SIFs evaluated using the current method are acceptably accurate.
