Abstract
This report presents results from a numerical characterization of mine blast loading performed using experimental data obtained from DRDC Suffield small pendulum apparatus trials. The validation of the IFSAS multiple material model was performed with data for two landmine trials representing the extremes in soil moisture content. The dependence of the applied impulse on the specific heat ratio and the soil stiffness was investigated. Results from the landmine model are qualitatively and quantitatively consistent with experimental results. The trend of increasing impulse with increasing moisture content was reproduced. The specific heat ratio was found to have little effect on the calculated impulse. Also, the soil stiffness was decreased from its default value for sand in an attempt to determine the effect of other lower-stiffness soil components such as clay. Results indicate a significant dependence on soil stiffness, and demonstrate the need for more detailed soil information prior to simulating detonations in soils.
