Spot welds are used extensively in the automotive industry to join panels, and car bodies
contain many thousands of spot welds. Different finite element models of spot welds have …

A hybrid structural stress method is presented for significantly simplifying spot weld
representations in fatigue evaluation of complex spot-welded structures while retaining a …

A new finite element assembly, to account for the structural behaviour of the region
surrounding a spot weld, is developed. The formulation derives from the analytic solution of …

A general theoretical approach based on theory of elasticity is presented in order to define
the structural behaviour of riveted and spot welded joints. The new closed form solutions …

Closed-form new structural stress and stress intensity factor solutions for spot welds in lap-
shear, square-cup, U-shape, cross-tension and coach-peel specimens are obtained based …

The theoretical framework and closed-form stress intensity factor solutions in terms of the
structural stresses for spot welds under various types of loading conditions are presented …

A procedure using a conventional stress value (ERS, equivalent radial stress) to evaluate
fatigue behaviour is applied to spot welded joints. The ERS is based on a closed-form …

This paper presents the design optimisation procedure for the automobile welds based on
the sizing optimisation technique. The purpose is to reduce the number of welds and save …

An analytical procedure for the evaluation of the elastic–plastic stiffness behaviour of spot
welded joints is presented. The procedure is based on a new model of spot weld region: a …

The present paper deals with the problem of numerical estimation of fatigue life in spot
welded structures. It is evidenced that the use of a particular suited analytical solution inside …
