The lately proposed, totally multi-scale conception of doublet mechanics, awarded the following in a self-contained shape, bargains unprecented possibilities to reconcile the discrete and continuum representations of solids whereas conserving an easy analytical layout and entire compatibility with lattice dynamics and continuum mechanics. Its functions comprise micro-electro-mechanical structures (MEMS), granular and particulate media, nanotubes and peptide arrays. Novel effects are mentioned, together with the identity of a brand new type of dispersive floor waves, and the presentation of tools for the experimental choice of the basic microstructural parameters. The relationships among doublet mechanics, lattice dynamics, and continuum theories are tested.

What's the very first thing that standard humans, for whom reporters are the proxy, ask once they meet a seismologist? it truly is definitely not anything technical like "What used to be the strain drop of the final earthquake within the Imperial Valley? " it's a sim ple query, which however summarizes the genuine calls for that society has for seismology.

Mon and M. 4 Energy Balance The differential formulation of energy balance for the material is r - div( q) + P + C - e = o. 12) In eqn. 12) r is the volume rate of heat supplied per unit volume, q is the heat flux vector, P and C are the mechanical and chemical power per unit volume, respectively, and e is the internal energy per unit volume. Of course, one could define r as a summation of heat supplies associated with each component, however, in this work, we elect to use the simpler definition given above.

Under some conditions (see, below, Sect. 2 the couple macrostresses Mij vanish. 47) to the equations of motion of the "symmetric" classical continuum. 49)2 become identities. ) eqns. 48) include different force macrostresses: u~f) in eqn. 47) and uW in eqn. 48). 48) at M > 1 become quite different from the equations of motion of both classical and Cosserat continua. 4 Alternative Formulation For later convenience, we express some of the equations developed in the previous sections in a more compact form.
