The Influence of Selected Parameters of Numerical Modelling on Strains and Stresses at Weld Toe Notch
Abstract
Latest development in the field of welding technology and prefabrication enabled massive production of thin-walled sandwich structures. Multi-layered sandwich structures are fabricated with the use of high-power CO2 lasers, friction welding, arc welding, hybrid welding, or other technique designed for the special purpose. Steel or aluminium alloy plates with thickness between 1 and 5 mm are connected by internal stiffeners. Strength analysis of such structures with the use of finite element method needs proper assumptions for numerical modelling. In this paper some crucial aspects of finite element modelling of steel sandwich panel tee-joint is analysed. The influence of modelling approach and the element size are being presented. The analysis shows some important possible simplifications in numerical modelling of laser welds which can be used for fatigue analysis (local stress approach, local strain approach).
