Abstract

While dealing with problems of impact analysis, where the force is dependent on the time, one can use the transient analysis to compute the response. Transient wave propagation has drawn interest from a long time mainly because of the way structural members behave when subjected to high rates of loading. Solutions to these problems find applications in the design of various mechanical equipments, or any situation where rigid objects are impacting on structural members.The first part of this study deals with the axial wave propagation in cones of different apex angles using transient analysis in ANSYS. The results from the ANSYS are compared with existing analytical and experimental data available from other studies. As the angle of the cone increases, the one dimensional modal theory fails to yield accurate results, due to lack of lateral inertia effects. The second part of this study is to examine at what angle the one dimensional theory for wave propagation ceases to be valid.
