ABSTRACT:
An apparatus for evaluating the ultimate strength of a plate of material includes a fixture for holding the plate and a loading element for applying a load to the plate, The fixture has a support element for supporting the plate at first and second points on the plate. The loading element is capable of applying a load to the plate at a third point interior to the first and second points on the plate. Another embodiment is a method for evaluating the ultimate strength of a plate of material having a front side and a back side. The method includes supporting the plate at first and second points on the plate and gradually applying a load substantially perpendicular to the back side of the plate at a point on the plate interior to the first and second points. The load is applied to the plate until the plate breaks, and the amount of load at which the plate breaks is noted to evaluate the ultimate strength of the plate.
