【 摘 要 】

This paper deals with the prediction of the penetration phenomenon of a cylindro-conical impactor on the ke;labepoxy-laminated composites using C eight-nded serendipity q&drilateral finite element based on first-order shear deformation theory (FSDT). Local as well as global deformations during impact is considered in the evaluation of indentation, penetration, and perforation phases. Local strains during impact have been evaluated using the hypothesis made from the available experimental observations of bulging during penetration. A detailed parametric study, considering various projectiles and target plate variables, has been carried out to find their effect on the response of the plate, and ballistic parameters, such as ballistic limit and absorbed energy.
