Meso mechanical analysis of effect of initial damage on ductile fracture initiation toughness of steel
初始损伤对钢的延性起裂韧性影响的细观力学分析
In conclusion , the research of this thesis indicate that the behavior of crack with a arc - tip is the same as that of a spiculate crack , but its load of fracture initiation is higher than the latter
总之，本文的研究结果表明，裂尖宽度为0 . 12mm的非尖锐裂纹的断裂行为与尖锐裂纹基本相同，但起裂载荷较高。
Based on lots of experiments , by combining the progress in mesomechanics with fea computation and analysis , this thesis investigated many parameters " effect on crack with an arc - tip in plain mixed - mode fracture , and compared existing criteria for fracture initiation , fracture direction and fracture mode transition
本文主要的工作是在试验的基础上，结合细观断裂力学当前的研究进展，通过有限元计算和模拟分析，研究了平面复合型断裂中各种力学参量对圆弧尖端裂纹断裂的影响，比较分析了现有的起裂判据、断裂扩展方向的判定方法以及断裂模式的转换条件。
