This grant is to provide 50 CRAY hours Supercomputer time on Class VI           computer to conduct modelling studies of the process of crack                   initiaiton and rapid crack propagation in semiductile and ductile               materials where the inelastic material response and material inertia            affect the load transfer characteristics.  The studies are intended to          provide detailed quantitative descriptions of the stress and                    deformation fields in the near-tip region and to relate these near-tip          descriptions to the overall structural behavior.  The computational             simulation study requires the computing power of a Class VI computer.           The computational results will help to establish criteria for crack             initiation, propagation, and arrest under dynamic conditions.
