Abstract:

A systematic study of predictive techniques for earth penetration has been reviewed. Based upon this study and industrial proprietary computer code, which appears to be the most flexible and extensible existing model currently available, has been used to examine controlled experimental data generated at AFATL. Results of this data analysis indicate that use of the code requires some judgment in proper selection of input parameters. In addition, test data generated at AFATL indicate that the drag coefficient in predictive soil penetration equations is velocity dependent over some impact regime and that soil viscosity is an important parameter in this region.
