Abstract

A convenient, experimental technique for evaluation of V-notch mode I STRESS INTENSITY FACTOR using the method of PHASE SHIFTING SHADOW MOIRE is described and demonstrated. In this study, the governing equations that relate the elastic solution and PHASE SHIFTING SHADOW MOIRE for mode I V-notch tip are derived in terms of material constants and the STRESS INTENSITY FACTORs. Then, a set of PHASE SHIFTING SHADOW MOIRE experiments were conducted on a polymeric tensile specimen and fringe patterns were captured. Through utilization of image processing techniques, phase map of fringe patterns was extracted and by analyzing the phase map, required data for determination of STRESS INTENSITY FACTORs were obtained. The obtained STRESS INTENSITY FACTORs by using PHASE SHIFTING SHADOW MOIRE method, demonstrates a good agreement with the FEM analysis of specimen.
