I have drawn the relation between dynamic stress intensity factor and crack tip velocity under mode-I impact loading for brittle material. In my research, some specimens were give nice results and I want to know:
Why is the dynamic stress intensity factor (DSIF) at initiation point not same DSIF at arrested point?
Why are almost the DISFs at arrested point always less than DSIF at initiation point of crack?
Why are DSIFs difference although they are same crack tip velocity?
Dynamic stress intensity factor (DSIF) at initiation
Dear All;
I have drawn the relation between dynamic stress intensity factor and crack tip velocity under mode-I impact loading for brittle material. In my research, some specimens were give nice results and I want to know:
Why is the dynamic stress intensity factor (DSIF) at initiation point not same DSIF at arrested point?
Why are almost the DISFs at arrested point always less than DSIF at initiation point of crack?
Why are DSIFs difference although they are same crack tip velocity?
I am very glad when give your comments;
Thanks
