Publikováno v: Powder Technology. 380:443-461

A new component of the combined finite-discrete element method (FDEM) is employed to estimate the effects of geometrical features, friction and energy dissipation parameters on the bulk properties of rigid pellet packs. This work constitutes the firs

A novel thermo-mechanical coupling approach for thermal fracturing of rocks in the three-dimensional FDEM

Autor: Clément Joulin, John-Paul Latham, Jiansheng Xiang

Publikováno v: Computational Particle Mechanics. 7:935-946

This paper presents a new three-dimensional thermo-mechanical (TM) coupling approach for thermal fracturing of rocks in the finite–discrete element method (FDEM). The linear thermal expansion formula is implemented in the context of FDEM according
