| 摘 要： | 受Rice的J积分的启发文中定义了空间体J积分,从三维角度定义了J积分的空间表达方式,并证明了文中定义的由闭合曲面表达的空间J积分具有守恒性,是对Rice的二维J积分理论的拓展和延伸,为研究求解含裂纹的弹塑性断裂问题提出了新思路.

| Abstract: | When Rice put forward J integral,not all people agreed with it.After a series of experiments,it was until 1972 that J integral had been accepted extensively.With the enlightenment of Rice J integral,the article defines space J integral which gives the space expression of J integral for three dimensions.It is confirmed the conservation of space J integral that is expressed by closed curved face.Space J integral enlarges and extends Rice's two-dimension J integral and offers a new idea for resolving the elastic-fracture with crack. |
