Abstract

Many plane stress finite elements which can exactly represent rigid‐body and constant‐strain modes are too stiff in their response to the simple flexural action of a beam. This problem has received considerable interest. In this paper we explore a new interpretation of the problem and show that the poor bending response of the original 4‐node plane stress quadrilateral can be quantitatively predicted by an error model.

In this article an experimental study to determine the longitudinal (or in-plane) shearing stress-strain response of a unidirectional fiber-reinforced composite material is presented. The test method used is the four-point bending of a 245" off-axis glass-fiber-reinforced laminate. Although a lamina

The paper deals with the symbolic integration of a 4-noded isoparametric finite element for plane elasticity. An efficient approach to generate explicit formulas for computing the elementary stiffness matrix is discussed. The procedure is based on the use of the Derive symbolic manipulation code as
