Energy density: Mechanics of solids (EDMS)
This special volume of TAFM on ‘‘Energy density: Mechanics of solids (EDMS)’’ arrives at a time where competitive advantage in science and technology calls the shots. The title of this special volume may not do justice to the theme that it intends to address although the volume should not be judged by its title. What needs to be said is that classical (solid) mechanics cannot stand as an island, paraphrased from John Donne. Solid mechanics is part of the whole of science and technology, including the classical and the quantum. The latter is also finding its way into application. The diverse concept of the classical and quantum is well recognized, though not understood. This should not be surprising since the same holds for the sustainability of macroproperties of solids affected by microstructuring and processing, in addition to changes of loading and geometry in service. Of course, the onion must be peeled layer by layer. Assemblage of the layers is similar to the multiscale segmentation in order to benefit macroscopically by microstructuring. These benefits have already found their ways into application based on the concept of equilibrium and homogeneity to achieve stability and durability. In this respect, the ‘‘Energy Density’’ is a very powerful tool. As an example, the supermaterial, graphene, is microsrtuctured with one atomic spacing network. Homogeneity mitigates local failure. Nonequilibrium and nonhomogeneity (NENH), however, are still the rule rather than the exception for the materials used to-day as cost effectiveness decides. When research and testing are short changed, mistakes are prone to cumulate and show up during manufacturing and in service conditions. Extensive case histories are available for the air-

craft manufacturing and the nuclear energy generation industry. The cow will die either by overfeeding financially or underfeeding technically. What has been said is not unrelated to this special volume. It serves as an indicator to the relevancy of the current research with respect to the priority of the society. The tentacles of solid mechanics can reach far while journal publication can act as the thermometer. Last but not the least, the Guest Editors would like to thank the contributors who made this volume possible and the anonymous reviewers who meticulously checked the papers providing useful comments aimed to improve the final version of the manuscripts. The invitation of the Editor-in-Chief is also gratefully acknowledged. Truly, TAFM Guest Editors of Speical Volume on EDMS June 5, 2014. George C.
