摘要
本文利用断裂力学中应力强度因子及能量释放率的观点,研究了柔性片撕裂试验,给出了临界撕裂力与临界应力强度因子(临界能量释放率)的关系,为预估各种撕裂的可能,提出可能的方法。
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.
