摘要
Hopkinson破裂是一种典型的应力波反射拉伸破坏现象,而目前有限元方法还不能很好地对这一现象进行模拟。在阐述数值流形方法的基本原理的基础上,利用其相应的程序对这一现象进行了模拟。模拟结果与理论分析结果相当吻合,这充分说明了数值流形方法在分析材料破坏问题方面的有效性。
Hopkinson rupture is a typical tensile failure phenomenon caused by the reflection of the stress wave, while this phenomenon can not be simulated perfectly using finite element method at present. On basis of introducing the basic principle of numerical manifold method, this phenomenon is simulated with its computer program of numerical manifold method. The results of simulation are in agreement with that obtained by theoretical analysis, so numerical manifold method is proved to be effective in analyzing the problem of material failure.
