Abstract

A procedure has been developed to investigate the nonlinear responses of composite plates under large strain and high strain rate loadings. A recently developed strain rate dependent micromechanics model is extended to account for the transverse shear effects during impact. Four different assumptions of transverse shear deformation are investigated to improve the developed strain rate dependent micromechanics model. The validities of these assumptions are investigated. The revised micromechanics model is then implemented into the higher order laminated plate theory which is modified to include the inelastic strain effect. Parametric studies are conducted to investigate the mechanical response of composite plate under high strain rate loadings. Results show the transverse shear stresses cannot be neglected in the impact problem. A significant strain rate dependency and nonlinear effects are found in responses of composite plate.
