ELASTIC DYNAMIC RESPONSE OF AXISYMMETRIC STRUCTURES,

Abstract

The finite element method coupled with a stable step-by-step integration procedure was used for the elastic dynamic analysis of two-dimensional plane strain solids. The computer program developed was machine independent and was designed to be used in the dynamic analysis of day-to-day engineering problems. The purpose of this investigation is to extend the step-by-step approach to the analysis of axisymmetric structures. In addition, new coding techniques have been introduced in order to increase the capacity of the program. Also, a higher order axisymmetric finite element has been developed which has significantly increased the accuracy of the procedure for the same numerical effort. Since the axisymmetric formulation reduces the plane strain case for a large radius, the present axisymmetric computer program replaces the original program. (Author)
