Experimental and numerical comparison of heat accumulation during laser powder bed fusion of 316L stainless steel

Autor: Mohsin Ali Chaudry, Gunther Mohr, Kai Hilgenberg

Publikováno v: Progress in Additive Manufacturing. 7:1071-1083

Heat accumulation during laser powder bed fusion (LPBF) of metallic build parts can adversely affect their microstructure and mechanical properties. To study the heat accumulation during 316L steel based parts manufactured by LPBF, a finite element m

Experimental and numerical characterization of expanded glass granules

Autor: Alexander Düster, Peter Wriggers, Mohsin Ali Chaudry, Christian Woitzik

Publikováno v: Computational Particle Mechanics. 5:297-312

In this paper, the material response of expanded glass granules at different scales and under different boundary conditions is investigated. At grain scale, single particle tests can be used to determine properties like Young’s modulus or crushing

On the computational aspects of comminution in discrete element method

Autor: Peter Wriggers, Mohsin Ali Chaudry

Publikováno v: Computational Particle Mechanics. 5:175-189

In this paper, computational aspects of crushing/comminution of granular materials are addressed. For crushing, maximum tensile stress-based criterion is used. Crushing model in discrete element method (DEM) is prone to problems of mass conservation
