OS1727 Estimation of Material Model Parameters of Iron Green Body

Abstract

In order to estimate parameters of the simulation model for iron green bodies of press-ready premix consisting of Distaloy AE, 0.5 % graphite and 0.6 % Kenolube, we carried out diametrical compression tests of the iron green bodies. We prepared the iron body with densities of 6.9 g/cm^3, 7.2 g/cm^3, 7.4 g/cm^3. The parameters of failure envelope in the modified Drucker-Prager Cap model were determined using the results of uniaxial compression tests in our previous study and diametrical compression tests.
