The nonlinear fracture behavior of quasi-brittle materials is closely related with the cohesive force distribution of fracture process zone at crack tip. Based
Fracture of Kirchhoff plates is analyzed by the theory of complex variables and boundary collocation method. The deflections, moments and shearing forces of the
The truncated expansion method for finding explicit and exact soliton- like solution of variable coefficient nonlinear evolution equation was described. The cru
