本研究的目的是建立三维模型， 复合材料层合板动态裂纹扩展和破坏机理 受到低速撞击。 这项研究将包括 变分一致断裂力学单元，多失效 标准和并行处理算法。 计算结果将与实验数据进行核对， 物体对复合板表面的低速撞击 和圆柱体。 由此产生的代码将提供一个定量的 用于预测复合材料层合板在低温下失效的设计工具 速度影响。

The objective of this research is to model the three-dimensional dynamic crack growth and failure mechanism in a composite laminate subjected to low velocity impact. This study will incorporate variationally consistent fracture mechanics elements, multi-failure criteria and parallel processing algorithms. The computational results will be checked with experimental data for low velocity impacts of an object on the surface of a composite panel and a cylinder. The resultant code will provide a quantitative design tool for predicting composite laminate failure under low velocity impact.
