| 摘 要： | 对单面粘贴FRP的带裂纹钢板进行了线弹性断裂力学分析,研究了裂纹尖端的应力强度因子变化,分析结果表明,经过FRP加固后,钢板的应力强度因子显著降低;随着FRP刚度的增加,应力强度因子逐渐减小。 |
| 关 键 词： | FRP 裂纹钢板 应力强度因子 有限元 |

| Abstract: | This paper analyzes linear elastic fracture mechanics of single FRP pasting steel plate with cracks,and studies the change of stress intensity factor at the top of cracks.Analytical results show that： after the reinforcement with FRP,the stress intensity factor of steel plate obviously reduces;with the increasing of FRP intensity,the stress intensity factor gradually reduces. |
| Keywords: | FRP steel plate with cracks stress intensity factor finite element |
