Detection of inclined edge crack in prismatic beam using static deflection measurements
- 12 Downloads
The effectiveness of a static deflection method for detection of an inclined edge crack in a prismatic cantilever beam is presented in this paper. A rotational spring is used to represent the flexibility due to the inclined crack. Two values of static deflections are needed for detection of crack location and rotational spring stiffness. The spring is positioned at the crack tip. Twenty-one mild steel specimens with various crack inclinations, locations and depths are used for experimentation. The experimental results confirm that the static deflection measurements can be used to predict the crack location of an inclined edge crack with acceptable accuracy.
