Abstract:

An experimental investigation was performed to define the soil response on three geometric shapes during impact. Two sizes of vehicles were utilized having plate, sphere and cone configurations with constant ratios of diameter, available surface contact area, and weight being maintained between each size. Impact velocity and mass were varied for each series of test vehicles. The acceleration-time history of the reactive soil forces on the impacting vehicle was recorded on an oscilloscope utilizing accelerometers as the sensing devices. Analysis was accomplished by computer program to obtain the magnitude of reactive force as a function of deformation. A modulus of deformation was determined as a constant for each geometric configuration. The magnitude of reactive force was a function of vehicle mass and impact velocity. Equations for the modulus of deformation and maximum reactive force were defined to permit prediction by extrapolation of the phenomenological behavior of larger vehicles. Author
