Abstract
A quadrilateral linear element for plane stress/plane strain analysis, formulated using a system of bars located at the Gauss integration points, is presented. A special bar element is formulated and the finite element is thereafter considered as an assembly of bars. The formulation presented is used in an attempt to explain the numerical problems arising when considering incompressible materials and reduced integration.
