About this event
Speaker: Dr. Bohumir Jelinek, Research Assistant Professor, Center for Advanced Vehicular Systems, Mississippi State University
This talk will present simulations for vehicle mobility in deformable soils using Discrete Element Method (DEM) performed at the Center for Advanced Vehicular Systems, Mississippi State University. Results of the DEM simulations using coarse-scale DEM soil models to predict tractive performance of a wheel in deformable soils will be shown and compared with published experimental data and empirical relationships.

George MasonG
Dr. George Mason worked for 33 years as a research engineer in the Mobility Systems Branch, Engineering Systems and Materials Division, Geotechnical and Structures Laboratory, as the Army’s lead researcher for studies on vehicle mobility. Later, he joined the Center for Advanced Vehicle Systems (CAVS) at Mississippi State University as a Research Civil Engineer. His work in mobility research was related to military areas, encompassing geospatial analyses, discrete element modeling of soils, and investigating vehicle/terrain interaction. The research required the application of advanced theories of soil physics and soil mechanics to quantify complex physical phenomena associated with the science and engineering of off-road vehicle mobility and the study of changes in associated surface geology.
