Modelling and updating of large surface-to-surface joints in the AWE-MACE structure
TL;DR: In this paper, the AWE-MACE model updating of joints is carried out using a sensitivity method using a layer of special interface elements having material properties that may be adjusted to improve the prediction of the complete model.

Fatigue Assessment of Welded Joints by Local Approaches
TL;DR: Local approaches applied to a seam-welded tubular joint are discussed in this paper, where the authors present a structural stress or strain approach for welded joints and a notch strain or crack propagation approach for seam welded lap joints.

Three-dimensional finite element analysis of the mechanical behavior of spot welds
Xiaomin Deng,Wei Chen,G. Shi +2 more
TL;DR: In this article, a detailed finite element solution of spot welds for various ratio values between the sheet metal thickness and spot-weld diameter was obtained from detailed analysis using the finite element method and used to provide a mechanics-based rationale for relevant experimental observations in the literature.
