ABSTRACT
A teaching and learning oriented 2D Finite Difference Simulator has been developed to visualize the interaction of elastic waves with user-defined inhomogeneities such as material inhomogeneities (cracks, notches, faults) and dissimilarities (interface cracks, delaminations, etc.), damageable solids, solids under initial stress or strain, impact due to various obstacles and blasting effects. The program runs swiftly on a personal computer and is extremely user-friendly. In a course on dynamic phenomena this software, in conjunction with lab experiments and assisted by an adequate theoreticalanalytical basis will provide students with a clear insight into dynamic fracture-wave interaction phenomena.
