Abstract
The impulsive responses of carbon fiber reinforced plastics(CFRP)-laminated plates are analyzed by using higher-order shear deformation theory and homogeneous anisotropic laminated plate theory. The plate of unidirectional prepregs is simply supported on all four sides and is hit by a spherical steel impactor at its center. The impact load histories are calculated numerically by using the nonlinear integral equation derived from Hertzian contact law. The strain histories of the plate are evaluated using higher-order theory and the numerical impact load histories obtained above. The theoretical results are in good agreement with the experimental results obtained by strain gauges and a piezoelectric transducer.
