| 中文摘要: |
| 本文采用基于杂交应力元和线弹簧模型相结合的方法,计算表面裂纹平板的应力强度因子。结果表明,本文解和三维有限元解吻合很好,与基于位移元和线弹簧模型相结合的解相比,具有更高的精度和较宽的适用范围。 |
| 英文摘要: |
| The estimation method based on hybrid stress element combined with line-spring model is used tocalculate the stress-intensity factors of surface cracked plates. The numerical results show that thestress-intensity factors given by this method are in good agreement with those by 3-D finite element method, more accurate than those by the method based on displacement finite element combined with line-spring model. |
