Writing on unintentional damage frequently turns out to ensue from one in every of views. One viewpoint is that of these inquisitive about points of damage prognosis and remedy and the opposite is that of these within the engineering and biologic sciences who speak about mechanical ideas and simulations. From our viewpoint, major details difficulties exist on the interface: folks within the enterprise of analysis and remedy don't know the best way to entry, use, and evaluation theoretical info that doesn't have noticeable useful applica­ tions; individuals at the theoretical facet wouldn't have sufficient real-life box info with which to spot difficulties or to guage options.
