| Abstract: | The problem is demonstrated on the base of main problem of cracks theory: the elastic plate with finite crack. The wellknown discrete solution of Dines, Paskin, Ortiz etc are compared with continual solution and hybrid solution of V. Novozhilov and K Thomson. The model of R Thomson and the model of V. Novozhilov are compared in detail. The identification the R-function of Novozhilov and lattice function of Thomson is proved. On the base of Thomson model the existence theorem of "fracture soliton". It is explaned the G.Cherny-V.Kozorezov effect of the loosing of resistance of medium. |
