Design & Analysis of Rivet Joints by using Different Geometrical Shapes

This project deals with riveted lap joints stress analysis. This work involves setting up and characterizing these joints for maximum use. Stress and fracture analyzes are carried out under both stress field and external tensile load using the finite element method. The riveting process and simulation of the lap joints subsequent tensile loading using a two-step simulation to determine the residue and overall stress state. The residual stress state due to riveting is obtained through maladjustment interference and clamping method. The effects of the riveting process parameters on the stress state are examined by using different values of interference and maladaptation. Two cracks, namely the semi-elliptic surface crack on the plate coating surfaces and quarter-corner crack from elliptical to rivet hole, are the most widely observed crack types in rivet joints. Fractured crack fracture analysis is performed by introducing these two types of cracks to a perpendicular plane at loading on the outer plate. Throughout the analysis of this work, the finite element technique was used. The present work has shown that riveted joints are superior in strengthening riveted joints. The riveted joint appears to reinforce and balance stress and to be distributed evenly. This improves riveting joints efficiency and life.
