Nonlinear Finite Element Dynamic Analysis of Axisymmetric Solids.
Abstract
The subject of this investigation has been the static and dynamic analysis of axisymmetric solids taking into account both material and geometric nonlinearities. A general Lagrangian formulation forms the basis for the incremental equations of motion which are solved using direct integration methods. Solution accuracy is improved by applying equilibrium correction loads at each step. Finite element discretization is achieved through the use of quadrilateral plane stress and axisymmetric elements with incompatible modes added for improvement of the element flexural characteristics. Several numerical examples are presented to demonstrate the effectiveness of the developed computer program. (Author)
