- A series of static and fatigue experiments which include lots of specimens are performed on bolted composite laminates that include different sizes , different lay orientations and different torques . dye - enhanced x - radiography is used to check the progressive damage process as evaluation techniques , which can be made nondestructively . finally , the ultimate strength and fatigue life of composite bolted joints in static tension and
