Title

Nonlinear Impact Analysis of Laminated Cylindrical and Doubly Curved Shells

Abstract

The nonlinear impact response of laminated composite cylindrical and doubly curved shells is analyzed using a modified Hertzian contact law. A finite element model is developed based on Sander's shell theory and includes shear deformation effects and nonlinearity due to large deflection. A nine noded isoparametric quadrilateral element is used to model the curved shell. The nonlinear time dependent equations are solved using an iterative scheme and Newmark's method. Numerical results for the contact force and center deflection histories are presented for various impactor conditions, shell geometry and boundary conditions.
