中文摘要:
      从边界虚拟力法出发.用缝面受集中荷载的解析解来构造裂缝单元,模拟压剪缝而复杂的剪力分布.直接解出各种复杂工程边界条件下拉压剪共存的多裂隙体问题.算例表明,这种解析数值解精度高、机时省,利于复杂条件多裂隙工程研究.
英文摘要:
      Taking departure from the boundary fictitious stress method and using analytical solution of the unit concentrated force applied to the crack surface, this paper deals with the crack element and the simulation of complex shear distribution along the cracking surface, and then it solves the engineering problems with various complex boundary immediately. Compared with other numerical time. One of the other advantages is its adaptability for a wide range of uses in engineering practice.
