Abstract

Presents a method of obtaining accurate response using the finite element analysis for linear elastodynamic problems under transient dynamic loading. The accuracy obtained would depend on the discretization of both space and time. An integrated method is presented where both space and time discretization errors are evaluated and iteratively converges to a solution of desired accuracy through adaptive refinement. In this paper, we propose to solve the response using Newmark-beta method. A number of examples are solved to demonstrate the effectiveness of the procedure.
