摘要
本文借鉴于 Perzyan 的基本思想及 Seaman 等人的实验结果提出了一个脆性材料动态断裂模型。利用本文的模型对Cochran 的实验结果进行了数值模拟,其计算结果比Cochran 的计算结果与实验吻合得更好。
By means of Perzyna's brittle dynamic fracture constitutive model and Seaman's experimental results, a new model of brittle fracture is put forward. Numerical calculations of uranium spall processes during impact is carried with the new model. The computations are in fair agreement with the experimental results.
