Latest Patents

Levy holds a patent for a Surface Displacement Measurement Gauge. This gauge is designed to measure an out-of-plane surface displacement profile around a cold-worked fastener hole. It relates to the distribution of residual compressive stresses around the hole and its impact on fatigue life. The gauge features a deformable strain sensor that can be positioned to conform to the out-of-plane surface of the structural material surrounding the cold-worked hole. A measurement reporting readout device communicates with the strain sensor, providing three-dimensional surface-profile measurement data. This data is crucial for determining or verifying the cold expansion magnitude, uniformity, and consequent fatigue life through advanced analyses.
