Comparative Analysis of Bolted Joint Assemblies Subjected to Cyclical Transverse Mechanical Stress
This research was conducted to determine the effectiveness of commonly-used washers in engineering structures by observing the difference in applied torque specifications and torque required to loosen bolted joint assemblies after being subjected to cyclical transverse mechanical stress. Two types of washers were tested: flat washers and split-ring helical lock washers. The physical concepts tested throughout this paper are theorized to scale to any size of bolted joint assembly. Based on the variables tested, the results are inconclusive. While the observed results did display the assemblies paired with split-ring helical lock washers required- on average- a greater force to loosen them, more extensive tests with improved means are needed in order to come to a more definitive conclusion.
