将线弹簧模型与其它一些数值方法相结合，提出了一种新的针对三维埋藏蠕变裂纹的计算模型，使分析过程避开了对裂纹尖端应力、应变场的直接考虑。同时，边界单元法不仅大大简化了计算过程，而且使计算结果仍具有相当的精度。本文还结合相应的一些实验数据进行了三维埋藏蠕变裂纹扩展的计算和预报。 Combining the linear spring model with some other numerical methods, a new computational model for three-dimensional buried creep crack is proposed, which avoids the direct consideration of stress and strain field in the crack tip. At the same time, the boundary element method not only greatly simplifies the calculation process, but also makes the calculation results still have considerable accuracy. In this paper, some corresponding experimental data are also used to calculate and predict the three-dimensional buried creep crack propagation.
