Tissue analogue selection for ballistic applications

Ballistic testing is of importance both in development of optimal protective systems, effectors and in post-event analysis (forensic ballistics). Where such testing is related to systems which may involve tissues in their designed use (for example, development of body armour systems), the choice of tissue employed is critical if effects are to be effectively captured. However, testing involving real-word tissues is inherently problematic from both ethical and fiscal (e.g. due to underpinning requirements / costs to enable it’s use) standpoints. To this end, utilisation of tissue analogues / simulants is preferred. However, there are numerous issues with such materials, ranging from their relative simplicity as often bulk in nature to the ability to accurately relate the performance of such surrogates to that of real-world tissues. This talk – to be given by Gareth Appleby-Thomas (Cranfield University) – will explore common tissue simulants drawing on both the literature and details of some of the work the speaker has conducted in this field over the last decade. It aims to introduce an overview of key analogue options, highlight some of the limitations of the same and briefly explore the behaviour of such materials in terms of the high-rate / ballistic-relevant impact response. Surrounding this, the speaker will also highlight some unusual insights into diagnostic response which have emerged from these studies.
