Part of the Fundamental Manufacturing Processes Video Series. Both mechanical and non-destructive tests are used to gage the quality of materials and parts throughout the manufacturing process. Mechanical tests are used to gather specific performance or property values of materials for part design purposes and quality control. These tests include: hardness, tensile, compression, impact, fracture, toughness, fatigue and creep. Nondestructive tests examine an object or material in a manner that does not impair it's future usefulness. The most common non-destructive tests include: visual inspection, liquid penetrant testing, magnetic particle inspection, eddy-current testing, ultrasonic testing and radiographic testing.
