A Study on Crack Tip Deformation and Ductile Fracture.
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.
