Abstract: A pressure indicating structure comprising (1) a translucent or transparent sheet including reflective structure defining at least a portion of a second surface of that sheet for reflecting back through a first opposite surface of the sheet light entering the sheet through its first surface, that reflective structure comprising a multiplicity of peak portions and recessed portions having recessed surface portions of the second surface that define recesses from the peak portions; and (2) a deformable layer comprising pressure sensitive adhesive having a major surface along the second surface of the sheet over the peak portions of the reflective structure. A predetermined pressure between the first surface of the sheet and the surface of the deformable material opposite the reflective structure can deform the pressure sensitive adhesive into the recesses to wet part or all of the recessed surface portions of the reflective structure thereby causing light to pass through the second surface along the wetted recessed surface portions instead of being reflected, which is visually observable to indicate that the predetermined pressure has been applied.

Abstract: A pressure indicating structure comprising (1) a translucent or transparent sheet having opposite first and second major surfaces, reflective structure defining at least a portion of that second surface for reflecting back through the first surface at an observation angle in a predetermined range of observation angles a visually significant amount of the light entering the sheet through its first surface, that reflective structure comprising a multiplicity of peak portions and recessed portions having recessed surface portions of the second surface that define recesses from the peak portions; and (2) a deformable layer comprising pressure sensitive adhesive, the deformable layer having opposite major surfaces with one of those surfaces defined by the pressure sensitive adhesive being along the second surface of the sheet adjacent and over the peak portions of the reflective structure and spaced from the recessed surface portions of the second surface. The shape and size of the peak portions and recessed portions of the reflective structure and the deformability of the deformable layer are selected or adapted so that a predetermined pressure is needed between the first surface of the sheet and the surface of the deformable material opposite the reflective structure to deform the pressure sensitive adhesive of the deformable layer adjacent the reflective structure into the recesses to wet part or all of the recessed surface portions of the reflective structure. Such wetting of part or all of the recessed surface portions of the reflective structure causes light to pass through the second surface along the wetted recessed surface portions instead of being reflected, thereby causing significant visually observable changes in the appearance of the reflective structure at an observation angle in the range of observation angles to indicate that the predetermined pressure has been applied.

Abstract: A device for monitoring the fatigue life of a structural member is comprised of at least one and preferably a plurality of substantially flat, elongated coupons which are fabricated of the same material as that of the member being monitored. The coupons are secured in parallel to the member so that they all experience the same strain history as the member. Each of the coupons includes a different stress concentrating notch pattern so that the application of the same strain to all of the coupons results in the development of different stress concentrations within the coupons. The development of different stress concentrations within the coupons causes each coupon to have a different fatigue life, the fatigue life of each coupon being a predetermined percentage of the fatigue life of the structural member being monitored.

Abstract: A test bearing is adapted from a standard production bearing for recording the location and magnitude of load applied to the bearing when installed and operated in its intended environment. A groove is typically formed in the stationary raceway of a cylindrical or tapered roller bearing and a relatively soft ductile wire is inserted into the groove. A plurality of axially spaced circumferential grooves may be fitted with wires for the determination of any potentional misalignment of the bearing. The bearing is then operated under normal conditions such that the inserted wires are plastically deformed. The extent of plastic deformation of the wire provides an accurate indication of the loading of the bearing.

Abstract: The invention relates to a fatigue indicator for mechanical parts subjected to repeated stresses, which comprises two thick elements spaced apart from one another and joined together by a thin web having a slit, these two elements being incorporated in the part or fixed thereto so as to move with respect to one another upon application of stress on the mechanical part in a plane which is parallel to the plane of the web, the thin web being thus subjected to a shearing stress in its plane, and wherein the slit of the thin web extends from one of the edges of the web in the direction of relative movement to a blind end so that, when the part is stressed, two cracks appear from corners of the blind end of the slit, extend progressively in the web and finish by reaching the opposite edge of the web or joining cracks coming from this opposite edge, the web thus being detached or practically detached.

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.
