Abstract

Simulate the stresses and strains in a composite laminate using laminated plate theory.  In-plane lamina properties, lamina thickness and stacking sequence must be specified.  Either force and moment resultants or mid-plane strains and curvatures must be specified.  The stresses and strains in the laminate and lamina coordinate systems are calculated.  The ABD matrix and reduced plane-stress stiffness matrices for each lamina are also calculated.
