Abstract

problem and its finite element approximation is introduced briefly. As for static results, contact force-indentation relations for composite plates are investigated to reveal the contact behaviors of composite plates and limitations of the modified Hertz contact law. For the dynamic case, the impact force histories of a composite plate by the present method are compared with the one by the modified Hertz contact law. Finally, impact force histories of curved composite laminates with various curvatures and stacking sequences are presented and are compared with those of plates with the same dimensions and stacking sequences. The curvature effects on impact behaviors of composite laminates are investigated. Governing Equations
