Abstract
The bending behavior of delaminated composite shallow cylindrical shells subjected to uniformly distributed load with corner-point supported, simply supported, and clamped boundary conditions is analyzed by the finite element method using an eight-noded isoparametric shell element. To ensure compatibility of deformation and equilibrium of forces and moments at the delamination crack front, a multipoint constraint algorithm is incorporated, which leads to an unsymmetrical stiffness matrix. Lamination, curvature and extent of delamination area are varied to compare the performances of delaminated cylindrical shells with those with no damage. The results are carefully observed and a set of conclusions is presented at the end of the article.
