“…Some studies focused on the geometric factors such as nugget diameter, length and width of a plate as well as the plate thickness [1][2][3][4][5][6][7][8][9][10][11][12]. It has been found that these parameters are primary factors influencing the tensile-shear strength and fatigue strength.…”

This paper describes local strain measurements of electrical resistance spot welds for three sheet stack-ups of Dual Phase (DP600) and Mild steel under quasi-static tensile loading. The experiments were designed to measure local strain distributions at the vicinity of the spot welds using a modified tensile-shear specimen geometry that allows a strain measurement system to access such area. The electrode tip type used was B-nose, and surface indentation levels were 30% and 50% of the sheet thickness. Local strains at critical locations in resistance spot welds were measured using non-contact 3D image correlation systems (ARAMIS) during quasi-static tension tests. The measured local strains were also compared with results offered by a finite element analysis.

This study presents the effect of the spot weld and sheets thickness on the fatigue life of the of the spot-weld joints to predict the lifetime and location of the weakest spot-welds due to the variable amplitude loading conditions. A simple model was used to illustrate the technique of spot-weld fatigue analysis. Finite element model and analysis were carried out utilizing the finite element analysis commercial codes. Linear elastic finite element analysis was carried out to predict the stress state along the weld direction. It can be seen from the results that the predicted life greatly influence the sheet thickness, nugget diameter and loading conditions of the model. Acquired results were shown the predicted life for the nugget and the two sheets around the circumference of the spot-weld at which angle the worst damage occurs. The spot-welding fatigue analysis techniques are awfully essential for automotive structure design
