THE INFLUENCE OF GENERALIZED BUBBLE DISPLACEMENT ON THICK PLATE RECTANGULAR ELEMENT

In this papal a universal method to establish high-quality rectangular element for both thin and thick plates is derived. In order to get higher precision, several generalized bubble displacements are introduced into the displacement pattern of element LFRI in 5,and two elements, C01 and C10, are constructed. Numerical examples show that the Present elements exhibit excellent perfomance.
