Abstract : An experimental investigation of elastoplastic crack tip deformation fields is carried out in aluminum specimens having one-dimensional variations in material strength in the vicinity of the crack tip in directions skewed to the crack axis. A comparison of the measured strains with proposed analytical results is presented. (Author)
