Numerical simulation of plasticity in double lap metallic bolted joints

چکیده
This article aims to compare three plasticity models, namely Bai-Wierzbicki (BW), von Mises and Drucker Prager, predict the failure modes in double-lap metallic bolted joints under shear loading. The joint finite element model has been validated against literature data, which demonstrated application of BW ductile fracture bolt prediction. Taguchi Design is used investigate effects geometrical parameters, preload stress triaxiality on modes. Force–displacement response amongst models differs up 20% when failing a different prediction mode (shear out vs. net section) same loading geometry conditions observed.

Strength Prediction in CFRP Woven Laminate Bolted Double-Lap Joints under Quasi-static Loading using XFEM
The current paper is concerned with modelling damage and fracture in woven fabric composite double-lap bolted joints that fail by net-tension. A 3-D finite element model is used, which incorporates bolt clamp-up, to model a range of CFRP bolted joints, which were also tested experimentally. The effects of laminate lay-up, joint geometry, hole size and bolt clamp-up torque were considered. An Ex...

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 کاملInvestigation on the Effect of Tigthening Torque on the Stress Distribution in Double Lap Simple Bolted and Hybrid (Bolted -Bonded) Joints
In this research, the effects of torque tightening on the stress distribution in double lap simple bolted and hybrid (bolted-bonded) joints have been investigated numerically. In order to determine the bolt clamping force value due to tightening torque in simple bolted and hybrid joints, which is necessary in numerical simulation, an experimental approach has been proposed. To do so, two kinds ...
متن کاملFailure Mode Analysis of Aluminium Alloy 2024-T3 in Double-Lap Bolted Joints with Single and Double Fasteners; A Numerical and Experimental Study
This paper aims to study the mechanical behaviour and failure mode of Al 2024-T3 in double-lap bolted joints. To accomplish this, the effect of geometric parameters was investigated in both configurations of single and double fasteners. Using ABAQUS/Standard, a three-dimensional finite element model was developed and verified against the experimental results of the joints loaded in tension. In ...
