| Abstract: | In this paper,based on the conception of stress intensity factor and energy release rate of fracture mechanics,the tear test of flexible sheet is dealt with.The relation between critical tear force and critical stress intensity factor(energy release rate)is obtained.Lastly the meth- od to estimate the possibility of tear of flexible sheet is given. |
