| 摘 要： | 通过对复合材料开孔板孔边的应力-应变分析,提出了一种可行性的方法求解应力集中系数,并通过计算得到应力集中现象的应力分布规律.应力数据由弹性理论求出,得到在一定范围内表示孔边应力集中系数的近似表述式.通过与ANSYS7.0求出的结果比较证明了该式的可行性和精确度. |
| 关 键 词： | 应力集中系数 弹性理论 复合板 有限单元法 |

| Abstract: | Theoretic analysis of the stress-strain on the compound board around the hole is made to put forward a feasible method of stress distributing law about the stress concentration.The stress data is obtained from elasticity.Approximate stress concentration factor on the board around the hole is expressed according to the effective data after calculating.A comparison with the theoretical values by ANSYS7.0 shows that the stress concentration factor is of high precision,so this method is feasible and accurate. |
| Keywords: | stress concentration factor elasticity compound board finite element method |
