The characterization of three-dimensional crack tip plastic deformation hence is important to assessment of susceptibility of cracks in structures. Three-dimensional elastic­ plastic techniques are available but application to complex problem are limited. To extend application of assessment of a new approach for three-dimensional crack tip constraint, a three­ dimensional constraint estimation scheme was examined for surface cracked plates with semi­ elliptical surface cracks under tensile and bending loads and deep and shallow through cracks. The J-llcr approach was found to be able to estimate the in-plane and out-of-plane crack-tip constraint along the semi-elliptical crack front by characterising the principal stresses over a dimensionless J/zcro parameter.
