A Simple and Sensitive Method of Monitoring Crack and Load in Three-Point Bending Fracture Mechanics Specimens Using Strain Gages

Abstract:

In fatigue crack growth experiment and fracture toughness test, the crack length measurement is very important. Here, this paper proposes a new method for measuring crack length, namely in the case of a known load, according to the strain on the front end face of the three point bending specimen would be to get crack length.
