Development of a lap joint fretting apparatus
WebMar 30, 2024 · Fretting is a phenomenon that occurs when two contacting surfaces are subjected to oscillating tangential forces. Zones of microslip develop along the contact surface where sliding occurs, leading to considerable surface damage. As a result, two main effects can be observed: Wear of the surfaces; A considerable reduction in fatigue life. WebFretting Fatigue Tests. 8. Analysis of Crack Propagation. 9.
