Experimental Analysis of Wear Characteristics in Natural Fibre Composite Materials
Abstract: In mechanical systems, energy loss and material degradation due to attrition are frequently the consequences of sliding contacts, which frequently lead to premature system failure. In this study, at 50°C, 80°C, and 110°C, the hardness was tested; the results showed that the values were 350.7, 422.5, and 455.5 HV, respectively. After conducting a high-temperature wear test, the mass loss of the as-deposited composite coatings was assessed by an electrochemical approach …

Stress Analysis of a Mechanical Joint from Recorded Data of a Single Component of Displacement
Abstract: The ability to fully stress analyze a pinned/bolted aluminum connector, including the contact stresses at the pin-plate interface, using measured displacement information is demonstrated. This is accomplished by using recorded data from only either one or the other of the two in-plane components of displacement. The relatively small pin-hole clearance results in the pin contacting the edge of the hole for an arc distance exceeding 180 degrees. Reliability of experimental …
