Adaptive finite element analysis of structures subjected to transient dynamic loads using time marching scheme

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, it is proposed to solve the response using Newmark-beta method. A numbers of examples are solved to demonstrate the effectiveness of the procedure.
