“…A review of different FE methods applied to welding processes is done by Marques et al in [22]. The goal of some of the methods is evaluating residual stresses in welded joints [23,24], or inherent deformations due to thermal effects [25,26].…”

Passive safety systems of cars include parts on the structure that, in the event of an impact, can absorb a large amount of the kinetic energy by deforming and crushing in a design-controlled way. One such energy absorber part, located in the front structure of a Formula Student car, was measured under impact in a test bench. The test is modeled within the Finite Element (FE) framework including the weld characteristics and weld failure description. The continuous welding feature is almost always disregarded in parts included in impact test models. In this work, the FE model is fully defined to reproduce the observed results. The test is used for the qualitative and quantitative validation of the crushing model. On the one hand, the acceleration against time curve is reproduced, and on the other hand, the plying shapes and welding failure observed in the test are also correctly described. Finally, a model that includes additional elements of the car structure is also simulated to verify that the energy absorption system is adequate according to the safety regulations.

“…Subsequently, the heat source model 9) , material modeling 10) and calculation techniques 11) have been developed, making it possible to clarify complicated phenomena. Recently, taking advantage of the progress of computers and algorithms, thermal elastic-plastic analysis has predicted the residual stress and the welding deformation of large structures that could not be clarified previously [12][13][14][15][16][17][18][19][20][21][22] . Since large structures often consist of multi-pass welding and three-dimensionally curved welding lines, the welding deformation behavior cannot be determined solely from simple angular distortion or transverse shrinkage.…”

“…Typical modes of weld-induced initial distortions in plated structures [11] [12]. World Journal of Engineering and Technology Studies on predicting the weld-induced initial distortions using finite element method are also found in the literature [23]- [28]. It was realized from the studies that the computing times are very expensive, and thus simplified methods using inherent strain have been suggested [27] [29] [30].…”

The objective of the present paper is to develop nonlinear finite element method models for predicting the weld-induced initial deflection and residual stress of plating in steel stiffened-plate structures. For this purpose, three-dimensional thermo-elastic-plastic finite element method computations are performed with varying plate thickness and weld bead length (leg length) in welded plate panels, the latter being associated with weld heat input. The finite element models are verified by a comparison with experimental database which was obtained by the authors in separate studies with full scale measurements. It is concluded that the nonlinear finite element method models developed in the present paper are very accurate in terms of predicting the weld-induced initial imperfections of steel stiffened plate structures. Details of the numerical computations together with test database are documented.
