Dr. Peter Kiss, Professor of Biosystems Engineering, Hungarian University of Agriculture and Life Science. Dr. Peter Kiss and Ph.D. candidate Nihal Salman discuss a state-of-the-art on load-bearing capacity of soil as a homogeneous finite half-space and ongoing research in terramechanics and land locomotion.

Dr. Paul Ayers, ISTVS Fellow, Biosystems Engineering Professor Emeritus, University of Tennessee. The Next Generation NATO Reference Mobility Model (NG-NRMM) provides an opportunity for the utilization of physics-based Vehicle Terrain Interaction models. This presentation provides the framework for possible vehicle-soil interaction components to assist model development. The physics-based components include tire placement, surface loading, stress distribution, time-dependent soil compression (multi-pass), preconsolidation stresses, soil rebound, lateral displacement, slip sinkage, and soil bulldozing.

Dr. George Mason, ISTVS Fellow, Center for Advanced Vehicle Systems, Mississippi State University. A general discussion of the uses of mapping and geographical information systems (GIS) to build an off-road simulation environment. We present the typical input data fields for models such as the NATO Reference Mobility Model (NRMM) and websites that contain information useful in defining the attributes. We discuss some of the temporal and spatial issues and future work in GIS.
