THE ELASTIC IMPACT RESPONSE OF GLASS EPOXY LAMINATED OGIVAL SHELLS/

This study examines the elastic response of glass/epoxy laminated comp osite ogival shells subjected to low velocity impact at an arbitrary l ocation by a solid striker. An analytic solution for prediction of tra nsient displacement and induced stress and strain is presented. This s olution, which has not been obtained previously, considers both contac t and transverse shear deformation. Based on this solution, the contac t force and transient strains induced in a shell by impact are studied . Impact experiments are also conducted on a simply-supported glass!ep oxy ogival shell and the resulting strain responses examined. The resu lts show that the contact force and strain response predicted using th e present solution agree well with experimental measurements. Copyrigh t (C) 1996 Elsevier Science Ltd.
