The study of ultrasonic wave phenomena for nondestructive                       evaluation (NDE) purposes requires precise numerical models to                  predict the transient elastic wave propagation and interaction by               arbitrarily shaped defects.  During the past two years the                      principal investigator has succeeded in developing a general                    purpose finite element code to solve the underlying equation of                 motion for two-dimensional plane-strain situations.  The program,               which is vectorized for a CYBER 205 system, is capable of                       accounting for realistic pulsed transducer signals and their                    interaction with arbitrarily shaped 2-D defects.                                                                                                                In order to investigate the feasibility of extending the current                2-D plane-strain computer code to a true 3-D model an initial                   need for 25 hours of cycle time on a CYBER 205/ETA 10                           supercomputer at Princeton University is requested.
