In recent years, the discrete element method (DEM) has been used to model bulk material,
especially brittle materials (such as rocks, ceramics, concrete, ice, etc.) with various …

Abstract Ceramic Matrix Composites (CMC) are advanced materials composed of ceramic
fibers embedded in a ceramic matrix, resulting in a highly durable and lightweight composite …

Abstract The Discrete Element Method (DEM), also known as distinct element method, is
mainly used to study divided media such as granular materials. Moreover, DEM is also …

This work presents the development of an explicit/implicit particle finite element method
(PFEM) for the 2D modeling of metal cutting processes. The purpose is to study the …

Ultrasonic vibration has a certain effect on the crack propagation tendency during sapphire
grinding, but the mechanism of the effect on the crack propagation tendency has not yet …

This thesis presents a methodology that enables the modelling and simulation of
dynamically interacting belt models in Discrete Element Method (DEM) simulations. In …

The introduction of ultrasonic vibration had a significant effect on the expansion tendency of
sub-surface microcracks, but the reason for influencing the expansion tendency of …

À l'échelle macroscopique, des matériaux tels que les roches, les bétons ou les céramiques
peuvent être considérés comme des milieux continus homogènes. Cependant, à l'échelle …

Sapphire has the characteristics of high hardness and low toughness, so it is very easy to
produce microcracks on the subsurface during grinding, which seriously affects the quality of …
