"Numerical simulation and modeling of buried explosives in soil is a challenging task and remains one of the critical gaps for assessing vehicle structural vulnerability to landmines. Defence Research and Development Canada – Valcartier has initiated a research program to focus on this problem. The aim of the project is to generate reliable experimental data to measure the distribution of the specific impulse generated by an explosive charge buried from different soil types and conditions and develop enhanced numerical models for the loading generated by these threats. This paper presents the experimental facility of a buried-charge impulse-gage concept and related finite element models developed for its study. Numerical simulations were performed using the LS-DYNA code to compare two loading methods. The initial data generated experimentally and the results from the FE models are compared with the analytical model predictions. Recommendations for improvement of the experimental facility are made"--Abstract, page i. Includes abstracts in English and French. Land mines Research Canada. Explosions Measurement Research Canada.
