Static Behavior of Damaged Composite Conoidal Shells Using Finite Element Method

Abstract

An extensive survey of past research work reflects that the static behavior of damaged composite conoidal shells has received very limited attention. Hence in the present work, static characteristics of composite conoidal shells with central delamination has been examined. Point loaded conoidal shells with simply supported and clamped boundary conditions are taken up. A finite element computer code using eight noded isoparametric elements has been developed and results are compared with those available from previous research. Further, more works have been done taking variation in boundary condition, aspect ratio, stacking sequences. Final conclusions have been drawn with help of extracted results and its meticulous investigation.
