Variation of crack propagation rate with resistance to crack movement
- 21 Downloads
It was shown experimentally that the resistance to brittle crack propagation determined from the value of parameter KID determines the rate of crack propagation, other conditions being equal.
It was found that an increase of resistance to crack movement (in terms of parameter KID) that is small in absolute value sharply reduces the rate of crack propagation.
