Abstract
A finite volume computational method using Eulerian formulation to simulate forging is adopted in this paper. By means of this finite volume method, an approach based on the “metallo-thermo-mechanics” to simulate metallic structure, temperature and stress/strain coupled with strain-induced phase transformation has been developed. The material is considered as elastic-plastic and takes into account phase transformation effects on the yield stress. The temperature increase due to plastic deformation, heat conduction and thermal stress has been co-analyzed. Strain-induced phase transformation, latent heat, transformation stress and strain are included. The applicability of the developed method was confirmed through a backward extrusion. The strain rate dependence of the flow stress is formulated, and the effects of strain rate on the austenitic-martensite transformation and the aggregate flow stress are examined.
