Stochastic Terrain and Soil Modeling for Off-Road Mobility Studies
… such data directly in the simulation. Dedicated modeling techniques and computational methods that realistically and efficiently simulate off-road operating conditions are thus necessary. Many studies have been recently conducted to identify effective and appropriate ways to reduce experimental …

Dynamic soil modeling in site response and soil-large pile interaction analysis
… problems; 1) one dimensional wave propagation in soil deposits and 2) the effects of lateral spreading on large pile foundations. Two new soil damping formulations are implemented in non-linear one-dimensional site response analysis for small and large strains. The first formulation introduces an …

Development of FEA wide-base truck tire and soil interaction models
… Recent advancements in computerized and virtual modeling provided an efficient methodology for accurate prediction of tire characteristics. In this thesis Finite Element Analysis (FEA) is employed as a method to accurately construct a new virtual wide-base tire model, validate it, and then study …

Classification, identification, and modeling of unexploded ordnance in realistic environments
… an in-depth study of the effects of permeable soil, modeled as a permeable half space, is presented. This study concludes that the discontinuity created by the air to permeable soil interface produces minimal effect in the response of a buried object. The change is limited to a magnitude shift …

Terramechanics of Saturated Clays: Assessing Tire Performance Through Experimental and Numerical Approaches
… in the challenging terrain of saturated clays. Modeling cohesive soils with high water content is challenging due to their low shear strength and highly deformable nature, necessitating systematic consideration in both material modeling and numerical techniques. Saturated clay is marked by high …
