✦ Synopsis

An efficient and accurate eight-node brick element is developed for linear static and dynamic structural analyses. In the element formulation, one-point quadrature is used so that computational time is substantially reduced without adversely effecting the accuracy. Hourglass control is provided to suppress spurious modes, and the stabilization parameters which must be specified by users in many other one-point quadrature elements are not required. An effective procedure to eliminate volumetric and shear locking is also developed. Several examples are presented to demonstrate the performance of this element.

A new four-node shell element with a single-point quadrature to be used for explicit time integration is presented in this paper. The physical stabilization is applied, which enables explicitly evaluating the stabilizing forces on basis of the general degenerated shell formulation and which does not
