    Thermoelastic Determination of Individual Stresses in Vicinity of a Near-Edge Hole Beneath a Concentrated Load

    Thermoelastic data are combined with an Airy stress function to determine the individual stresses on and near the boundary of a circular hole which is located below a concentrated edge-load in a plate. Coeffic...

    Combining Thermoelastic and Stress Function Data to Evaluate Individual Stresses Around a Near-Edge Hole

    The individual stresses are determined on and near the edge of a hole immediately beneath but close to a concentrated edge load in an approximate half-plane. Experimental thermoelastic data is combined with Ai...

    Characterization of the panoramic annular lens

    The panoramic annular lens (PAL) consists of a single piece of glass, with spherical surfaces, that produces a flat annular image of the entire 360-deg surround of the optical axis of the lens. This paper desc...
