本文计算了在平面应变条件下,承受突然施加的轴向拉伸荷载的中心裂纹试样的瞬态的应力场和位移场。我们用有限单元法解动力学基本方程,采用Perzyna粘塑性本构方程。
In this paper, the transient stress field and displacement field of a central crack specimen subjected to a sudden applied axial tensile load under plane strain conditions are calculated. We use the finite element method to solve the basic equations of the dynamics and use the Perzyna viscoplastic constitutive equation.
