Abstract:

Near tip strains and crack tip opening displacements were both measured with the moire method and calculated with Finite Element Analysis. The equivalent stress intensity factor of a small specimen loaded into general yielding is related to its crack tip strains and stresses. Its relations to the overall deformation of a specimen and the applied stress are also obtained by the near tip stress and strain correlation. Its application to a ductile aluminum is illustrated. In addition, crack tip opening and crack tip advancing were calculated based on the shear separation mode of the unzipping model.
