Inconsistency in 9 mm bullets : correlation of jacket thickness to post-impact geometry measured with non-destructive X-ray computed tomography [PDF]

, 2014
Fundamental to any ballistic armour standard is the reference projectile to be defeated. Typically, for certification purposes, a consistent and symmetrical bullet geometry is assumed, however variations in bullet jacket dimensions can have far reaching ...

What Is the Return on Investment of Digital Engineering for Complex Systems Development Schedules? Findings From a Mixed‐Methods Case Study on the Post‐Production Design Change Processes of Navy Assets

Systems Engineering, EarlyView.
ABSTRACT Complex engineered systems routinely face schedule and cost overruns, along with poor post‐deployment performance. Both INCOSE and the U.S. Department of Defense (DoD) have championed Digital Engineering (DE) as a potential remedy, yet most of DE's purported benefits remain anecdotal, and its return on investment (ROI) remains poorly ...

Exploring the Landscape of MgO Polymorphs: Stability and the Electronic Band Gap of Promising Candidates

Zeitschrift für anorganische und allgemeine Chemie, EarlyView.
In this study, we have investigated possible predicted polymorphs of magnesium oxide (MgO) with respect to their thermodynamic and kinetic stability, as well as their electronic properties, focusing on the possibility of tuning the band gap of the material.

Preparing to Fight the ‘Wrong War’? Why the UK Defence Budget Must Focus More on ‘National Resilience’

The Political Quarterly, EarlyView.
Abstract This article argues that the current debate over defence spending in the United Kingdom is fundamentally flawed. Too much emphasis is being placed on preparing for a form of warfare with Russia that is unlikely to occur. As this article points out, the Russians actually want to avoid a traditional battlefield confrontation with NATO.

Sticky Pixels: Evolutionary Growth by Random Drop Ballistic Aggregation [PDF]

, 2001
Over the years many techniques have been developed for simulating and modelling trees, ferns, crystals and natural structures. Indeed, many complex and realistic images have been formed.

3D‐printed wound channels

Journal of Forensic Sciences, EarlyView.
Abstract Although soft tissue simulants are widely used in ballistic research, glycerine soap is the only material that offers a clear view of the temporary cavity of a wound channel without the use of optical apparatus. However, the latter still shows some inconvenience mostly on its weight and its dehydration process when cut, making it challenging ...
