Seawater is an extremely persistent, surprisingly corrosive force that causes a multitude of complex problems when it comes to use and maintenance of maritime vessels. Any equipment that is exposed to seawater on a regular basis is especially vulnerable and must be rigorously maintained if it is to function reliably. At the same time, any…
When considering catastrophic failures in structures, one often imagines the worst-case scenario, in which a large force can cause an immediate destruction. However, events of these types are rare in nature. More often, a structure succumbs to fatigue failure long before any major destructive event can befall it. This fatigue can be an insidious threat…

Recent advancements in additive manufacturing (AM) have allowed the technology to move from simple prototyping using plastics to creating fully formed metallic components that can be integrated into modern aerospace systems. AM presents a revolution in traditional manufacturing methods by removing the limitations of traditional casting subtractive manufacturing processes. AM provides designers and engineers the…
With recent advances in medical technology and combat casualty care, today’s wounded warrior (such as the one discussed in the companion article, “An Account of a Future Wounded Warrior,” on page 5) is being supported with state-of-the-art treatment materials and techniques never before seen. As a result, critical injuries can be repaired more rapidly; nonrecoverable…
