摘要：

The mechanical behavior of spot-welds under tensile-shear for one, three and five spot-welds is investigated in detail. Volumetric approach is applied to find fatigue life duration of welded spots. The three-dimensional finite element models for different geometries, including gap effects and non-linear features of materials are applied to obtain fatigue life. The elastic-plastic stress distribution at edge of hot spot-weld is considered and effective stress, effective distance and notch strength reduction factor are obtained. The comparison between experimental and volumetric approach reveals good agreement with real fatigue life. (C) 2003 Elsevier Ltd. All rights reserved.
