Pereira, L.F. (author), Weerheijm, J. (author), Sluys, L.J. (author)Although many aspects of the fracturing process of concrete are now well understood and successfully simulated with various models, it is still very difficult to properly simulate the different failure mechanisms observed in a concrete structure induced by ballistic impact. In this paper, an enhanced version of the effective-rate-dependent...article 2018

van 't Hof, C. (author), van Erkel, A.G. (author), Pape, G. (author)An analytical model is developed for analysis of the dynamic elastic-plastic response of structural stiffened panels (e.g. bulkheads) due to blast. The model accounts for pinned boundaries and panel aspect ratios in the range of 1 – 5. Both the short span and long span deflection shapes are accounted for, as well as stiffeners in both directions...conference paper 2018

Longbottom, A. (author), Verreault, J. (author), Cargill, S. (author), Milne, A. (author)Many explosives are fuel rich and on detonation produce excess hydrocarbon species that may subsequently burn with oxygen in the surrounding air. This process is known as afterburning and takes place on relatively long timescales compared to detonation. An example is TNT which releases more than twice as much energy from afterburning as it does...conference paper 2018

Dijkers, H.P.A. (author), Hooijmeijer, P.A. (author)Ammunition transshipments are a key part of the logistical operations of the armed forces and are often executed via ships. These transshipments pose a risk to the people present in the area surrounding the harbor, where the loading/unloading of the ship takes place. A method is presented to perform a quantitative risk assessment of such...conference paper 2018

(author)There is limited knowledge on deriving the strength of an explosion based on the observed explosion effects. Existing methods are based primarily on the effects of blast overpressure on surrounding structures.

van Hulst, M. (author), Langenberg, J.P. (author), de Klerk, W.P.C. (author), Alblas, M.J. (author)The toxicity of smoke-generating ammunition can be established by looking at the complete hand grenade or only at the smoke composition. In this paper both approaches are described. The toxicity of a signalling smoke was assessed as a complete smoke hand grenade whereas for a 76 mm screening smoke canister only a red phosphorus (RP) pellet was...article 2017

van Driel, C.A. (author), de Klerk, W.P.C. (author)Conventional gun propellants exhibit the phenomenon of nitrocellulose (NC) decomposition. Besides an effect on thermal stability of propellants, decomposition of NC has an effect on the mechanical integrity of the propellant grains. Enhanced grain fracture may lead to unacceptable changes of the pressure build-up. The effect of ageing on NC...conference paper 2017
