Abstract

Abstract

A continuum damage constitutive model for the fiber-reinforced laminate was introduced. Penetration of the fiber-reinforced laminate by a flat-ended projectile was numerically simulated by using the 3D finite element software LS-DYNA. Residual velocity of the projectile, deformation and failure modes of the laminate under impact loading were predicted. Evolvement and distribution of the different damage modes were obtained. Simulated results are in agreement with those of the ballistic tests.
