Both the Royal Navy and the Royal Netherlands Navy are using the 30 mm Goalkeeper as CIWS (Close-In Weapon System) on their ships. The Goalkeeper CIWS and its ammunition are being used since the late 1980’s. Before introduction in the Royal Navy and the Royal Netherlands Navy, the Goalkeeper system and its ammunition have been studied...

The use of lightweight composite armour concepts is essential for the protection of future combat systems, both vehicles and personal. The design of such armour systems is challenging due to the complex material behaviour. Finite element simulations can be used to help understand the important design parameters. A material model of Dyneema, a...

Now that an industrial-scale low-cost production route for ballistic-grade titanium is within reach, the potential use of titanium armour could depend on a solution for the spalling of high strength titanium. This paper addresses a titanium based metal laminate as being a possible solution for the use of titanium in armour concepts. Autodyn-2D...

TNO executed a technology demonstration programme in co-operation with RWMS on the application of solid fuel ramjet propulsion technology to medium calibre air defence projectiles. From 2000 to 2004 a complete and integrated structural and aero-thermodynamic projectile design was conceived satisfying the gun related requirements on projectile...

The use of lightweight systems is essential for future combat systems. More and more steel structures are replaced by composite structures. This also influences the vulnerability of the platform. A finite element material model is created in Autodyn of the carbon fiber reinforced plastic (CFRP) AS4/3501 in order to predict both the residual...

The Dutch Ministry of Defence has asked TNO to study mine neutralisation by small calibre projectile impact. This method would not demand the close approach of a suspected object. A single shot with a high accuracy weapon at a large stand-off will eliminate the danger and will allow for close approach to inspect the object after observing the...

Through-the-thickness crack propagation in thin-walled structures is dealt with in this paper. The formulation is based on the cohesive zone concept applied to a kinematically consistent shell model enhanced with an XFEM-based discontinuous kinematical representation. The resulting formulation comprises the representation of continuous...

In the area of hydrogen safety, research facilities are essential for the experimental investigation of relevant phenomena, for testing devices and safety concepts, as well as for the generation of validation data for the various numerical codes and models. Within the framework of the European HySafe Network of Excellence (NoE), the 'Integration...

Data on the dynamic fracture energy of concrete are scarce and also not consistent due to different test methods, data analyses and definitions. In [1] the authors summarized and evaluated the test methods. Suggestions for the standardization of dynamic tensile testing were given. In the current paper the discussion is continued. First,...

As is the case for all armed forces, the Netherlands’ MoD requires new weapons and munitions to be qualified according to existing rules and regulations. However, to date no generally accepted qualification process for Non-Lethal Weapons (NLW) exists, and suitable test and assessment protocols for different types of NLW are needed. Even for the...

Ever since WWII transparent armour consists of a multi-layer of glass panels bonded by thin polymer bond-films using an autoclave process. TNO has worked on the development of innovative transparent armour concepts that are lighter and a have better multi-hit capacity. Two new transparent armour concepts are described; glass-clad polyurethane...

This paper presents a time integration scheme capable of simulating blast loading of relatively high frequency on porous media, using coarse meshes. The scheme is based on the partition of unity finite element method. The discontinuity is imposed on the velocity field, while the displacement field is kept continuous. The velocity discontinuity...

Models for calculating human injury from a blast wave are examined. The Axelsson BTD model is able to give injury estimates also for complex shock waves, but is difficult to use in practise since it requires input from four pressure sensors on a BTD (Blast Test Device) in the specific location. To find the injury in other places, a new...
