NUMERICAL-ANALYSIS OF 2-DIMENSIONAL STRESS WAVES IN TRANSVERSE ISOTROPIC CYLINDER DUE TO LONGITUDINAL IMPACT

A numerical method to analyze two-dimensional stress waves in a transv erse isotropic cylinder is presented, when an axisymmetric impulsive l oad is applied to the end surface of the cylinder. For the numerical a nalysis of two-dimensional stress wave propagation, the finite differe nce method based on integration along the bicharacteristics is employe d. From the numerical results obtained by this method, it has been con firmed that the proposed method can be applied to analyze two-dimensio nal stress wave propagation in a transverse isotropic medium. The effe ct of the transverse isotropy on the propagation of stress waves in st ainless steel-aluminum composites is also demonstrated.
