The symposium will address how results from one scale can be shifted or related to another scale, say from macro to micro or vice versa. This will be accomplished via a meso zone such that the transition from one scale to the next are made smooth via stress (or force) and displacement compatibility conditions. Multiscaling is modeled  much like a microscope such that the magnification factor can be changed, except that this is done analytically. The results of cross scaling are interactive and shown to be governed by highly non-linear equations in continuum mechanics. This is a new topic that is not well known up to now. The closest field to this topic is Mesomechanics which is also a relatively new field in order to meet the demand of how to treat devices in microns.

The disciplines in classical mechanics and physics rarely consider relating the results at the different scales such as macro to micro or to atomic. Although much discussions have been alluded to this subject, little progress has been made because of the non-equilibrium nature of the problem when size is made very small. The new approach retains the use of the equilibrium mechanics within a scale level such that cross scale results can be connected by scale invariant criteria. In this way the level of presentation can be kept at the level where most engineers can grasp within a short period of time.
