“…To date, various numerical simulation approaches have been developed for SMF processes. They can be classified as the discrete element method (DEM) [ 46 , 47 ], boundary element method (BEM) [ 48 ], finite volume method (FVM), finite difference method (FDM) [ 49 ], finite element method (FEM) including crystal plasticity finite element (CPFEM) [ 50 , 51 , 52 , 53 ], extended finite element (XFEM) [ 54 ], multi-grid and mesh-free methods [ 55 ], fast Fourier transformation (FFT) [ 56 ] and arbitrary Lagrangian-Eulerian (ALE) [ 57 , 58 ].…”

Lightweight sheet metals are attractive for aerospace and automotive applications due to their exceptional properties, such as low density and high strength. Sheet metal forming (SMF) is a key technology to manufacturing lightweight thin-walled complex-shaped components. With the development of SMF, numerical simulation and theoretical modelling are promoted to enhance the performance of new SMF technologies. Thus, it is extraordinarily valuable to present a comprehensive review of historical development in SMF followed by state-of-the-art advanced characterization and modelling approaches for lightweight metallic materials. First, the importance of lightweight materials and their relationship with SMF followed by the historical development of SMF are reviewed. Then, the progress of advanced finite element technologies for simulating metal forming with lightweight alloys is covered. The constitutive modelling of lightweight alloys with an explanation of state-of-the-art advanced characterization to identify the constitutive parameters are presented. Then, the formability of sheet metals with major influencing factors, the techniques for measuring surface strains in SMF and the experimental and modelling approaches for determining the formability limits are clarified. Finally, the review is concluded by affording discussion of the present and future trends which may be used in SMF for lightweight metallic materials.

“…The thermomechanical simulation of the forging process makes it possible to determine the local distributions of the state of strain, stress, and also temperature (Bednarek et al, 2012;Łukaszek-Sołek, 2014;Perez, 2018). The information obtained this way is sufficient for determining parameters, which guarantee the possibility of the process conducting and a product having the required quality (Guo et al, 2018;Saad et al, 2018). Numerical modelling in the case of the designing of a new forging or perfecting the one applied till now aims at predicting the manner of material flow, the analyzing of the impression die filling, determining of the areas of the possible defects formation, and also optimizing the dimensions of an initial material (Gao et al, 2019;He et al, 2017; -90 -COMPUTER METHODS IN MATERIALS SCIENCE Skripalenko et al, 2019).…”

High demands made by customers and the need to reduce production costs while maintaining high quality of products brings the necessity to include specialized models and criteria in the numerical analysis of forging processes. The latest approaches offered by commercial software manufacturers do not include comprehensive analysis of defects. In many cases is necessary to include user subroutines dedicated to specific forging operations. Interdisciplinary knowledge allows selection of creation of forecasting technique typical for analyzed forging process. The main purpose of the review article is to show the latest tools, their modifications and extensions for predicting defects typical for forging processes and often observed in the industrial process using FEM modelling. The authors showed that additional parameters or functions can support the conventional stress and strain parameters to extend the possibilities of interpretation, e.g. by means of postprocessor subroutines. Various forging processes, typical defects and optimized method of their forecasting were presented. The research methodology was a combination of numerical modelling, laboratory tests and analysis of industrial processes.
