Ballistic and physical properties of highly fractured alumina [PDF]
, 2010 It is known that ceramic materials in armour are often shattered by a penetrating projectile and the resistance to penetration is therefore dependent upon the properties of this failed material.

Probable Circular Error (CEP) of Ballistic Missiles [PDF]
, 1966 The survival of our nation, during a nuclear exchange, depends upon an effective national defense structure. The prime weapon system in this defense structure is the ballistic missile.

steel research international, EarlyView.The high‐strain‐rate behavior of resistance spot‐welded DP800–DP1000 joints is investigated. Results show that microstructural gradients across BM–HAZ–FZ govern hardness, strain rate sensitivity, and failure modes. While strength increases with strain rate, energy absorption is controlled by ductility, with DP800–DP800 joints showing superior ...

A Thoracic Mechanism of Mild Traumatic Brain Injury Due to Blast Pressure Waves [PDF]
, 2008 The mechanisms by which blast pressure waves cause mild to moderate traumatic brain injury (mTBI) are an open question. Possibilities include acceleration of the head, direct passage of the blast wave via the cranium, and propagation of the blast wave to

Flight Path Angle Steering with Lambert Guidance Reference [PDF]
فصلنامه علوم و فناوری فضایی, 2010 In this paper a new guidance technique for ballistic missiles and launch vehicles is proposed. Generally the Lambert guidance is used to generate missile nominal (correlated) parameters through powered flight to put it in a ballistic flight path. Because

The Reflexive Turn in Systems Engineering: A Disciplinary Response to Complexity
Systems Engineering, EarlyView.ABSTRACT The Future of Systems Engineering (FuSE) programme has called for the discipline to evolve as a transdiscipline capable of engaging complex eco‐socio‐technical challenges. Yet the pace of that evolution has been slower than the arguments for it would predict. This article examines why.
