A Study on the Transient Response of a Stepped Column Subjected to an Impact Load

Abstract

This report presents the results of studies on the stiffness variation effects to the structures such as ship, missile and airplane subjected to an axial or a vertical impact load. The theoretical studies were carried out for a simply supported beam under an axial compressive load and a cantilever beam under a vertical load. A transient analyses for beams and cylindrical shells were performed, and the results were evaluated. It was also investigated the effect of frequency variation of an impact load on the response of structures. A finite element modeling and a numerical analysis were performed by MSC/PATRAN and MSC/NASTRAN program.
