Abstract

Different structural elements of automobiles, ships, aircraft wings and fuselages, turbines, nuclear reactors, and other machine components are susceptible to variable loading condition. Due to this type of loading situation all the mentioned structures are undergone to the formation of internal cracks, these cracks will be grown and eventually lead to the failure of the structures. Hence, the fatigue phenomenon due to variable loading conditions is a major threat and has come into address with the technological development that happening is now a days. To avoid the failure of structures due to fatigue loading condition structures are provided with different fasteners like rivets, bolts, tack welds, etc. In this study, the structures analyzed are cantilever beams, the fasteners considered are rivets, the loading considered for analysis is fully reversed cyclic loading, and the analysis considered is the fatigue analysis, the mode of analysis is a simulation using FEA software named ANSYS R19.2 WORKBENCH software. The variable parameters considered are rivet diameter, load, and coefficient of friction at the common interface of riveted specimens. Here in this analysis, the beam dimensions are kept constant. Besides, in this study, the comparison of fatigue life for solid and riveted cantilever beams of identical dimensions is presented. The material considered for the rivets and beams is aluminum alloy.
