Verreault, J. (author), Leerdam, P.J.C. (author), Weerheijm, J. (author)The calibration of a user-defined blast model implemented in LS-DYNA is presented using full-scale test rig experiments, partly according to the NATO STANAG 4569 AEP-55 Volume 2 specifications where the charge weight varies between 6 kg and 10 kg and the burial depth is 100 mm and deeper. The model calibration is performed on the specific...conference paper 2016

Verreault, J. (author), Roebroeks, G.H.J.J. (author), Weerheijm, J. (author)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...conference paper 2016

Westerhof, T.A.T. (author), Huebner, M. (author), Ferretti, D.L. (author), van Doormaal, J.C.A.M. (author), Gebbeken, N. (author)Determination of the structural response of a structural element under blast loading is of interest to vulnerability / lethality (V/L) studies of military operations in urban terrain. These studies require a quick and easy to use method to simulate the structural response of e.g. a wall under non-uniform loading conditions. The single degree of...conference paper 2016

Boonacker, B. (author), Halswijk, W.H.C. (author), Westerhof, T.A.T. (author), Eeuwhorst, T.R. (author), Verhagen, T.L.A. (author)TNO is developing a flexible blast effects module suited to be used in simulations of MOUT scenarios within a VL simulation environment for assessing structural damage and human injuries due to blast load-ing. VL simulations should run in seconds to enable Monte Carlo simulations as well as deal with various ammunition – target engagement...conference paper 2015

van den Berg, A.C. (author), Eggen, J.B.M.M. (author), TNO Prins Maurits Laboratorium (author)Despite many fundamental objections, TNT-equivalency methods are widely used for simple vapour cloud explosion blast modelling. Presently, however, the TNO Multi-Energy method is increasingly accepted as a more reasonable alternative. Applying the Multi-Energy method, blast can be modelled by the specification of an equivalent fuel-air charge,...conference paper 1996

Prins Maurits Laboratorium TNO (author), Absil, L.H.J. (author), Kodde, H.H. (author), Weerheijm, J. (author)Noise pollution around military training facilities caused by firing of explosives, artillery or large caliber guns poses a severe problem to neighbouring communities. One possible way to attenuate the blast is the construction of blast walls close to the explosion center. This paper describes a combined experimental and numerical study of the...conference paper 1995

van Wingerden, C.J.M. (author)Een onderzoek is uitgevoerd naar tengevolge van gasexplosies ontstane dynamische belastingen op constructies. Hiertoe werden twee situaties onderscheiden, te weten : 1) de explosie vindt plaats in het inwendige van de contructie of : 2) de explosie vindt plaats buiten de constructie. Voor interne gasexplosies kan de maximaal te verwachten...book 1986
