Webmicro-to-macro transition, starting from discrete data and translating the particle information into continuum elds. From the discrete side, Discrete Element Methods (DEM) … Webmicro–macro transition step is especially challenging for non-uniform or dynamic situations. Here, we present a gen-eral method of performing this transition, but for simplicity we will restrict our attention to two-component scenarios.

Micro origins for macro behavior in granular media SpringerLink
Webbetween the micro-scale and macro-scale variables and functions): the micro-macro transition. This enables the development of continuum models that contain infor-mation about the micro-structure of the granular materials without the need for a priori knowledge. The micro-macro transition will be illustrated with two granular ow problems: WebMar 23, 2024 · In the first part, I will summarize how granular microstructures correlate to two types of collective behavior of granular media: spatial phase transitions of … indoor golf simulator facilities
A framework for micro–macro transitions in periodic
WebApr 13, 2024 · To achieve this objective, first, new generation procedures of the HCP ball array for the 2D DEM models were proposed; second, a theatrical approach that was used to transition from material macro-properties to contact micro-parameters values in the 2D DEM models were derived based on the basic configuration and mechanism of discrete … WebOct 15, 2024 · This work develops an approach that leverages data from an expensive simulator that explicitly resolves the behavior of microcracks to build a machine learning model of the impact of the microcrack on the elastic moduli that provides accuracy comparable to HOSS but is four orders of magnitude faster than HOSS. 2 PDF WebThere have been rapid advances in technology both to investigate the microscopic properties of soils, and to simulate their granular behaviour explicitly through Discrete Element Method (DEM). DEM was originally used to reproduce element tests, but it is now being advocated for boundary-value problems. indoor golf simulator installation
