| 摘 要： | 本文在文献1],2]的基础上对Reissner型板进行分析,发现与经典板理论类似的近似方程用于求解Reissner型板的断裂问题是有效的,并用能量法解得受弯边裂纹和中心裂纹板的应力强度因子。将结果与文献3]比较表明,用本文的近似方法求解应力强度因子方法简便且精度较高。

| Abstract: | On the basis of the literature 1] and 2] , an approximate method is proposed for computing stress intensity factor in a cracked Reissner's plate. In this method, the equations are similar to that of classical plate. The equations are solved by energy method and the results are compared with the literature 3] . It shows that this method is quite accurate and easy to be used. |
