Abstract: Abstract. A reliable simulation tool capable of predicting off-road mobility on complex granular deformable terrain is essential for vehicle design and performance evaluation. However, the use of high-fidelity computational ...

Abstract: A new hierarchical multiscale terrain model is developed using the material point method (MPM) to enable effective modeling of large terrain deformation for high-fidelity off-road mobility simulations. Unlike the Lagrangian ...

Abstract: A hierarchical multiscale off-road mobility model is enhanced through the development of an artificial neural network (ANN) surrogate model that captures the complex material behavior of deformable terrain. By exploiting ...
