Moiré of crack-opening interferometry in adhesive fracture mechanics

  • Kenneth M. Liechti
Article

Abstract

A moiré of crack-opening interference patterns, accomplished in real time with digital image processing of video images, is used to subtract the residual-stress effects due to the mismatch of thermomechanical properties and cure shrinkage that are usually present in bonded systems. The technique was used to measure the opening-mode strain-energy-release ratese associated with a number of interface cracks in a blister-test configuration. The results are compared with an approximate analysis for the total strain-energy-release rate.
