The joint fretting apparatus allows studying the fretting behavior of mechanical joints under quasi-static and dynamic loading conditions. The proposed design fulfills the requirements listed in Table 1 and possible misalignment errors are continuously (in-situ) monitored by this apparatus. See more Static weights were used to calibrate the load cell. Ten different weights ranging from 0.2 to 20 lbs—0.89 to 89 N were systematically imposed on the load cell, and force readings were recorded. The sensitivity obtained … See more Full transfer of the imposed displacement at the PZT actuator tip to the joint samples is nearly impossible due to the inherent compliance of the … See more The noise level was checked by conducting experiments with the aluminum monolithic joint sample.

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. foam stadium seat cushionsWebLaser Induced Stress Wave Thermometry for In-situ Temperature and Thickness Characterization of Single Crystalline Silicon Wafer: Part I-Theory and Apparatus. 51:1103-1114. 2011; Development of a Lap Joint Fretting Apparatus. 51:1405-1419. 2011; Computational Analysis of a Cross-linked Actin-like Network. 49:91-104. greenworks battery powered chainsawsWebEriten, M., Polycarpou, A.
