Abstract
A rectangular non–conforming element based on Reddy’s higher-order shear
deformation plate theory is developed. Although the plate theory is quite attractive
but it could not be exploited as expected in finite-element analysis. This is due to
the difficulties associated with satisfaction of inter-elemental continuity requirement and
satisfy zero shear stress boundary conditions of the plate theory. In this paper, the
proposed element is developed where Reddy’s plate theory is successfully implemented.
It has four nodes and each node contains 7 degrees of freedom. The performance of the
element is tested with different numerical examples, which show its precision and range
of applicability.
