摘要
本文应用有限单元法计算了动态内压下含裂纹厚壁筒的动态应力强度因子K_1(t),提供了合理的计算方案,研究了不同动载参量对动态应力强度因子的影响。文中提供了一种计算动态K_(t)因子的近似积分法,方便于各种形状动载内压曲线下的动态应力强度因子的计算。
In this paper, the finite element method was used to compute the dynamic stress intensity factor of thick-walled cylinder with edge crack. The suitable programme and the factors affecting dynamic stress intensity factor was studied. A simple reumercal intergal method for computation of dynamic stress intensity factor was proposed. Jt is convenient to compute stress intensity factor for arbitrary profile of dynamic loads.
