Abstract

A coupled mechanical and thermal analysis of powder during the warm compaction process has been investigated. This paper presents the development of the numerical model to generate a green compact through uniaxial die compaction. The powder is considered to be the rate independent thermo-elastoplastic material. The constitutive laws are derived based on a continuum approach and the governing equations are developed where the thermal strain is taken into account together with elastic and plastic strains. The Elliptical Cap failure criterion is considered to model the yielding of the material during the process. A large displacement based finite element approach is used considering an updated Lagrangian strategy. The non-linear systems of equations are solved employing the staggered-incremental-iterative solution strategy.
