Abstract

In the present investigation the Sanders shallow shell theory in conjunction with the Reissner-Mindlin shear deformation theory are employed to develop a finite element analysis procedure to study the impact response of doubly curved laminated composite shells. The finite element method employs the nine-noded quadratic isoparametric elements of Langrangian family. The results obtained from the present analysis are compared with those in the literature. Numerical results are obtained for cylindrical and spherical shells to investigate the effects of various parameters, such as radius to span ratio, span to thickness ratio, boundary condition and stacking sequence on the impact behavior of the target structure.
