Abstract: Determining the state of the ground is critical for Objective Force operations. Currently, no methods exist to remotely, and accurately, measure the near-surface soil properties (strength, density, compressibility, and texture) needed to define ground state. Analysis of low-velocity impact probe deceleration, obtained during penetration, is the most practical method to remotely determine ground state. Development of the physics describing the behavior of the impact requires in-depth knowledge of the physical properties of the relevant soil. This report provides an extensive suite of calibration and verification material properties for predicting the response of an ASTM C33 sand to low-velocity probe penetration. The experimental program determined the following physical properties for this sand: elastic behavior (shear and Young’s moduli and Poisson’s ratio), strength characteristics (friction angle, cohesion, compressibility, and triaxial strength), and construction parameters (maximum/minimum densities, optimum moisture content, and California bearing ratio).
