Evaluation of Fatigue Life Reduction Factors at Bolt Hole in Double Lap Bolted Joints Using Volumetric Method
In this research, the influence of bolt preload on the fatigue strength of 2024-T3 aluminium alloy double lap bolted joints has been studied experimentally and numerically. To do so, three sets of the specimens were prepared and each of them subjected to tightening torque of 1,2.5 and 5 N-m and then fatigue tests were conducted under various cyclic axial load levels. In the numerical method, th...
متن کاملOn the Influence of Riveting Process Parameters on Fatigue Life of Riveted Lap Joint
In this paper, influence of riveting process parameters, namely, riveting force, sheet thickness, friction coefficient and clearance fit are investigated on residual stress field and fatigue life of single riveted lap joint of AA2024 type. According to the effect of riveting induced residual stresses on fatigue life of riveted lap joint, these parameters are optimized to maximize the residual s...
متن کاملThree–dimensional Stress Analysis of the T–bolt Joint
A three-dimensional finite element model of the joint has been developed. The model has been used to predict the stress field of the laminate in the joint area, assuming homogeneity and linear behavior of the material. The modeled geometry is a T-bolt that joins a coupon of glass fiber–epoxy and a block of steel. The results obtained from the model have been verified experimentally using both e...

متن کاملFatigue growth of multiple-cracks near a row of fastener-holes in a fuselage lap-joint
The fatigue growth of multiple cracks, of arbitrary lengths, emanating from a row of fastener holes in a bonded, riveted, lap joint in a pressurized aircraft fuselage is studied. The effects of residual stresses due to a rivet misfit, and of plastic deformation near the hole, are included. A Schwartz Neumann alternating method which uses the analytical solution for a row of multiple colinear cr...
