The Journal of Terramechanics publishes articles on the interaction between vehicles/machinery and deformable surfaces, such as terrestrial terrain, seabed, and extraterrestrial soils; and on the terramechanics-vehicle-environment impact topics and applications, including modeling and simulation with verification and validation; design and control; and operation and testing with statistical confidence of crewed and uncrewed off-road vehicles of various levels of autonomy, robots, extraterrestrial rovers, and terrain engaging-earth moving machinery, the latter of which implements working with agricultural soil/crop systems, construction equipment, forestry machinery, and tools for extraterrestrial surface exploration.As the publishing organ of the International Society for Terrain-Vehicle Systems (ISTVS), the journal provides a forum for disseminating the latest scientific and technical information in the field by both members and non-members of ISTVS. The journal presents a cross-section of technical papers, reviews, comments, and discussions, and serves as a medium for recording recent progress in the field.
