ABSTRACT
The present work is a comparative study of adaptive and Arlequinmeshing methods applied to tensile testing and metal forming for Inconel 625 alloy at elevated temperatures. All engineering problems are modelled using finite element (FE) methods, which discretize a continuous system into discrete small systems by resulting in discretization error. Identification of exact discretization error is vital for improving FE results, and it is generally assessed by adaptive meshing. Numerous adaptive techniques have been suggested in the literature, such as hierarchical, polynomial and relocation adaptivity, and these methods are employed in tensile testing, deep drawing, spring back and stretch forming. Furthermore, the Arlequin approach is implemented with three adaptive techniques, and the effectiveness of meshing strategies is evaluated by comparing with experimental results to identify the combination with the best accuracy and least computation time.
