Analysis of Stress Concentration That Occurs in the Reform with Finite Element Method

Abstract

This research analyzes the concentration of stress that occurs in the reform by a finite element method. The reform looks like C-clamp used in the compression rear axial drive’s flange. SolidWorks and Cosmos programs are used for modeling and analysis respectively. The comparative results between actual tests and finite element method had error 8.1%. It is concluded that the model of finite element method can be used in this problem’s analysis. Analyses adjust pressure at 230, 270, 300, 350, 380 bars. It is found that stress concentration at the neck is 227, 265, 289, 354, 382 MPa. The safety factors of the neck are 2.3, 2.0, 1.8, 1.5, 1.38 respectively. Stress concentration will be direct variation with reduced pressure. If increasing radius of curvature is not fixed at the neck, it can reduce the stress concentration.
