This paper reports the application of the p-version finite element method to the dynamic analysis of thin/thick composite laminate systems. The principle of dimensional reduction is used in the formulation to accurately model the three-dimensional behavior so that the geometrically two-dimensional character of the problem is maintained. A computer program was developed using FORTRAN to calculate the time history using Newmark`s direct integration scheme. The accuracy of the results have been evaluated with reference to closed form analytical solutions and excellent agreement is noted.
