|Title:||A Lagrangian Cell-Centred Finite Volume Method for Metal Forming Simulation||Authors:||Cardiff, Philip; Tuković, Željko; Jaeger, Peter De; Clancy, M.; Ivankovic, Alojz||Permanent link:||http://hdl.handle.net/10197/7939||Date:||7-Sep-2016||Online since:||2017-08-06T01:00:11Z||Abstract:||The current article presents a Lagrangian cell-centred finite volume solution methodology for simulation of metal forming processes. Details are given of the mathematical model in updated Lagrangian form, where a hyperelastoplastic J2 constitutive relation has been employed. The cell-centred finite volume discretisation is described, where a modified discretised is proposed to alleviate erroneous hydrostatic pressure oscillations; an outline of the memory efficient segregated solution procedure is given. The accuracy and order of accuracy of the method is examined on a number of 2-D and 3-D elastoplastic benchmark test cases, where good agreement with available analytical and finite element solutions is achieved.||Funding Details:||Bekaert||Type of material:||Journal Article||Publisher:||Wiley||Journal:||International Journal for Numerical Methods in Engineering||Volume:||109||Start page:||1777||End page:||1803||Keywords:||Finite volume methods; Lagrangian; Plasticity; OpenFOAM||DOI:||10.1002/nme.5345||Language:||en||Status of Item:||Peer reviewed||This item is made available under a Creative Commons License:||https://creativecommons.org/licenses/by-nc-nd/3.0/ie/|
