Access equipment and 100 CPU hours on the Gray XMP/24 at Boeing                 Computer Services will be obtained and very detailed finite element             solutions for plane strain growing cracks will be generated.  The               computations will determine the evolution of the near-tip stress and            deformation fields during stable crack growth and estimate its                  functional dependence on the crack growth history.  Crack growth                simulations will be performed for a deeply cracked bend geometry under          conditions which progress from small scale to large scale, including            yielding.  Accurate numerical description of the near-tip fields will           be sought for different judiciously chosen load versus crack length             histories.  The overall goal is to utilize these results on ductile             crack growth equations and verify them with experimental results.
