Assessing the consequences on task performance due to the kinetic threat

The theater of war is continuously evolving, however the kinetic threat (fragments and bullets) remains a prominent threat to current and future warfighters. To support the development, procurement and use of personal protection equipment (PPE) against these types of threats, ICARUSII (Integrated CAsualty RedUction Simulation environment) has...

Assessment of the secundary fragments from buried explosives

Different test methods are used to assess the performance of personal protection equipment (PPE) against secondary debris, such as soil, grid and stones, ejected when a buried improvised explosive device (IED) detonates. However no standard scientific test and evaluation methodology exists for this type of threat. One of the reasons is the...

Modeling and experiments on ballistic impact into UHMWPE yarns using flat and saddle-nosed projectiles

Yarn shooting experiments were conducted to determine the ballistically-relevant, Young’s modulus and tensile strength of ultra-high molecular weight polyethylene (UHMWPE) fiber. Target specimens were Dyneema® SK76 yarns (1760 dtex), twisted to 40 turns/m, and initially tensioned to stresses ranging from 29 to 2200 MPa. Yarns were impacted,...

The development of a ballistic method for simulating fragments from buried explosive devices

No standard scientific methodology currently exists to assess the performance of personal protection equipment (PPE) against secondary debris, such as soil, grit and stones, ejected when a buried improvised explosive device (IED) detonates. Different test methods are used for this evaluation. The PPE can be placed around a buried explosive...

Forensic analysis of explosions: Inverse calculation of the charge mass

Forensic analysis of explosions consists of determining the point of origin, the explosive substance involved, and the charge mass. Within the EU fP7 project Hyperion, TNO developed the Inverse Explosion Analysis (TNO-IEA) tool to estïmate the charge mass and point of origin based on observed damage around an explosion. In this paper inverse...

A structured approach to forensic study of explosions: The TNO Inverse Explosion Analysis tool

Forensic analysis of explosions consists of determining the point of origin, the explosive substance involved, and the charge mass.

Defeating the RPG7 threat by using electric power in reactive armour applications

Shaped charges are considered to be a big threat. The Dutch army frequently encounters shaped charges like RPG7 while operating in countries like Afghanistan and Iraq. Conventional armour offers only limited protection against these types of threats, within the weight restrictions. One possible countermeasure is electric reactive armour (ELRA)....

Finite element simulations and experiments of ballistic impacts on high performance PE composite material

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...

On the assessment of V0 and V50 of body armour from one series of ballistic impact experiments

The characterisation of the level of protection of personal body armour against impact of a particular projectile is usually expressed by the V50. However, from the point of view of protection, V0is a parameter more suitable than the V50 to indicate the protective capabilities of the body armour. As there exists an extensive database with V50...
