Analysis of Knuckle Joint for Structural Steel, Aluminium Alloy, And Titanium Alloy

Abstract—The goal of this research is to investigate and determine the stresses in a knuckle joint using steady state analysis, with the objective of identifying the optimal material for the project. Three different materials, namely structural steel, aluminium alloy, and titanium alloy are analyzed for the knuckle joint. The study focuses on a knuckle joint designed for an applied force of 25 KN. Finite Element Analysis (FEA) results for tensile loading are compared and validated with total deformation. The findings indicate that the knuckle joint made of titanium alloy exhibits the lowest stresses, while the knuckle joint made of structural steel is capable of sustaining the highest tensile load without failure.
