Experiments and Modeling of High Strain Rate Effects in Sands and Clays.
Abstract
The objectives of the proposed research program are to obtain experimental stress-strain data over a range of confining pressures and loading velocities, and to develop and verify a comprehensive time dependent model for soils base on the results of the experimental phase. This model will capture time effects, such as loading rate effects, creep, and relaxation, as well as any combination of these, which are all required for realistic modeling of projectile penetration into soils. Testing will be conducted under both drained and undrained boundary conditions to simulate in-situ conditions where soil is located above and below the ground water table. Testing will also be conducted on both sands and clays to fully explore cohesionless and cohesive soil types. The experimental program will consist of four separate programs that will be performed at different confining pressures and loading velocities. The four different programs are associated with different types of experimental equipment, some at different geographical locations.
