Abstract : Elastic and plastic interlaminar shear deformation in a laminated fibrous composite was studied by means of a finite-element method. A composite element, constructed of orthotropic membranes separated by shear- resisting media, is developed and utilized. The effect of interlaminar shear deformation at the free edges of solid laminates and laminates containing a cutout is presented. (Author-PL)
