Abstract

This study tracks the development of an analytical model, designed to investigate the dynamic response of a composite sandwich plate subjected to a low-velocity impact. The model is based on the thick anisotropic plate theory, developed by Reddy and Pagano, which takes into account a through-thickness shear. An indentation law, as proposed by Hertz, is used to model the local response under the impactor. The good correlation between the shock and the simulation results testifies the validity of the method as far as the prediction of the contact force and the shear deformation in the core are concerned.

复合材料夹层板冲击损伤预测

本研究跟踪了一个分析模型的发展，旨在研究复合材料夹层板在低速撞击下的动态响应。该模型基于Reddy和Pagano提出的厚各向异性板理论，该理论考虑了贯穿厚度的剪切作用。采用赫兹提出的压痕律来模拟冲击器作用下的局部响应。冲击与仿真结果的良好相关性证明了该方法在预测岩心接触力和剪切变形方面的有效性。
