Materials used to manufacture composite components and structures must be tested, assessed and certified to meet a variety of mechanical requirements. Finished parts also must be tested to make sure they meet dimensional requirements.
Dr. Donald F. Adams compares the three basic types of shear-loaded compression test fixtures.
