Numerical Analysis of Two-Dimensional Stress Waves in Transverse Isotropic Cylinder due to Longitudinal Impact

A numerical method to analyze two-dimensional stress waves in a transverse isotropic cylinder is presented, when an axisymmetric impulsive load is applied to the end surface of the cylinder. For the numerical analysis of two-dimensional stress wave propagation, the finite difference method based on integration along the bicharacteristics is employed. From the numerical results obtained by this method, it has been confirmed that the proposed method can be applied to analyze two-dimensional stress wave propagation in a transverse isotropic medium. The effect of the transverse isotropy on the propagation of stress waves in stainless steel-aluminum composites is also demonstrated.
