摘要：

Calculations of impact response in composite material structures are important in damage-tolerant design. In general, impact of composite structures is a complicated event, and it is important to assess the accuracy of the calculation. The present work attempts to address this point by comparing the results of different solution techniques. One of the techniques is based on a Rayleigh-Ritz approach with numerical integration in time, and another is an analytical approach using Laplace transformation of the governing differential equations, but requiring a linearization of the contact deformation. The results are also compared with finite element calculations and experimental measurements. The results show the range of numerical parameters required to give good accuracy of solution. © 1990.
