ABSTRACT:
The present paper examines an improved quadrilateral strain based element that satisfies both
compatibility and equilibrium equations in order to give supplementary amelioration. This element has
two degrees of freedom (d.o.f) at each corner node in addition to the central internal node. The
performance of this element is tested by applying it to the analysis of the problems used in previous
publications. The efficiency of this element was established and the convergence of the results for
stresses and displacements to a satisfactory degree of accuracy was shown to be faster when compared
with those obtained by other quadrilateral elements.
