by

From discrete particles to solids – about sintering and self-healing Stefan Luding Multi Scale Mechanics, CTW, UTwente, POBox 217, 7500AE Enschede, NL. DOI: https://doi.org/10.7494/cmms.2011.1.0312 Abstract: In this review, particulate materials are studied using the Discrete Element Method (DEM), where the particles keep their identity throughout. Loose particles can sinter due to time-, stress- or temperature-dependent … Read more
