Scaled blast loading simulations on different vehicle bottom geometries

The development of new bottom concepts for military vehicles against mine blast threats involves the consideration of two main aspects: the bottom geometry and the material used. In order to reduce costs, experimental testing of new vehicle bottom concepts often requires small-scale setups together with numerical simulations to assist the design and development process. This study first presents the validation of a numerical blast model for bare charges using experimental freefield blast data. An investigation of the reflected pressure on a flat plate shows the
