distribution of stress concentration factors along the weld toe of tubular kt-joints in truss bridges
many research works have been accomplished so far on the computation of stress concentration factors (scfs) for various types of tubular joints. almost all these studies have focused on values of the scf at the saddle and crown positions, and they have ignored the hss at other locations along weld toe. however, scf distribution is very important for predicting the fatigue crack growth, determin...
متن کاملFinite Element Analysis of Effect of Weld Toe Radius and Plate Thickness on Fatigue Life of Butt Welded Joint
Mechanical parts during service may be subjected to cyclical loading and high stresses, which make fatigue life prediction extremely important. The finite element method is commonly used in research institutions and industry in order to estimate life span of mechanical parts. In this study, an experimental investigation of the geometrical dimensions and mechanical properties of a weld joint, an...
متن کاملResidual Stresses in Butt and Socket Welded Joints
A finite element scheme for simulation of welding residual stresses is presented in this paper. Detailed thermal and residual stress analyses for butt-welded and socket-welded pipes are performed using ANSYS and ABAQUS. The calculated distribution of axial stress and hoop stress at welded joint are validated against experimental results. Furthermore, residual stress relaxation under high amplit...
متن کاملFatigue Strength Assessment of Welded Joints by Using Notch Stress Approach
The fatigue strength assessment of welded joints by using the known parent material fatigue strength is considered in this paper. The stress concentration factor was determined performing FEA of singlesided transverse attachment joints for mean value of weld toe radius which was calculated by using several measurements of the weld toe radius along the weld length. The fatigue strength of welded...
متن کاملEvaluating Weld Magnification Factor in Welded Tubular Joints Using Artifitial Neural Networks
In welded tubular joints, when the fatigue crack depth is less than 20% of chord wall thickness, the crack growing process is highly affected by weld geometry.
 Hence, T-butt solution and weld magnification factor (Mk) are applicable tools for evaluating the crack growth rate in this domain. In this research, the capability of Artificial Neural Network (ANN) for estimating the Mk of weld toe...
