Using a newly developed boundary layer theory for laminated compos ites, a complete analytical solution is obtained for all the interlaminar shear stresses as well as the normal or "peel" stress of a finite strip in unidirec tional extension. Results obtained by the present analysis are compared to the finite-difference solution of Pipes and Pagano, and to the analytical solution of Puppo and Evensen.
