A large strain thermoviscoplastic formulation for the solidification of SG cast iron in a green sand mould

摘要

This paper presents a large strain thermoviscoplastic formulation for the analysis of the solidification process of spheroidal graphite (S.G.) cast iron in a green sand mould. This formulation includes two different non-associate constitutive models in order to describe the thermomechanical behaviour of each of such materials during the whole process. The performance of these models is evaluated in the analysis of a solidification test. (C) 2001 Elsevier Science Ltd. All rights reserved. [References: 51]
