| Abstract: | In this peper, the caustics parameter equations of mixed mode crack and the unstable extension trajecory have been provided. The numerical analysis and experimental investigation of the unstable extension trajectory of crack are given by using C type specimen. The results of this investigation are useful for the monitor of crack and design of arresting crack in the practice. |
