Abstract
An apparatus and method adapted to enhance the structural performance of a desired connection and provide a readily perceivable indication of predetermined limitations having being reached prior to actual failure of a connection. A method for enhancing structural performance of a desired structure by preventing fracture propagation.
Claims7
A method for enhancing the fatigue life of a structure comprising:
- forming a crack-stop hole in said structure;
- inserting a plug in said crack-stop hole;
- applying a mechanical vibration to said plug such that said plug is deformed inside said crack-stop hole, thereby causing said crack-stop hole to undergo expansion;
- wherein said expansion of said crack-stop hole enhances the fatigue life of said structure.
