Abstract

The mechanical behavior of spot welds under tensile-shear and symmetric coach-peel loading conditions is investigated in detail. The focus of the analysis is to reveal inherent three-dimensional features of the stress field in spot welds and to understand their effect on the structural performance and static failure modes of the spot welds. The findings of this investigation are obtained from detailed finite element solutions of spot welds for various ratio values between the sheet metal thickness and spot-weld diameter. These findings are then used to provide a mechanics-based rationale for relevant experimental observations in the literature. This study is carried out using the finite element method.
