Abstract:

A finite-element model based on the assumed stress hybrid method is derived, including the effect of transverse shear deformation, for moderately thick laminated plates made of fiber reinforced composite materials. Three general quadrilateral elements are derived and are shown to yield accurate displacement solutions for a variety of laminated plate examples. The computer subroutine for calculating the stiffness matrix of each element is capable of handling any moderately thick laminated plate, the sole requirement being that each lamina have at least tetragonal material properties. This subroutine, coupled with appropriate finite-element assembly and solution routines, can be used to solve problems of arbitrary static loading and boundary conditions. Author-PL
