Abstract: A contact gauge utilizable for determining contact pressure conditions between two bodies at their interface including a thin plastic sheet capable of memorizing an induced birefringence and a thin, load transmitting member attached to the sheet for inducing the birefringence therein. A method of employing the contact gauge for determining the contact pressure conditions between the two bodies also forms a part of the present invention.

Abstract: A fatigue damage indicator includes a thin plate mounted between or integral with two members to which a stress is to be applied, the disposition of the two members being such that the thin plate is stressed in shear.Slots extending in the direction of the applied stress may be provided to ensure that cracks formed by fatigue stress propagate in a desired direction and the crack propagation is designed to ensure that a part of the plate becomes detached or is bent substantially away.
Abstract translation: 疲劳损伤指示器包括安装在两个构件之间或与要施加应力的两个构件成一体的薄板，两个构件的布置使得薄板在剪切中受到应力。 可以提供在施加的应力方向上延伸的槽，以确保由疲劳应力形成的裂纹在期望的方向上传播，并且裂纹扩展被设计成确保板的一部分脱落或基本上远离弯曲。
