Abstract
Recently, with the progress of technology, we will inevitably face some
problems of materials on the mesoscopic scale. On the other hand, with the
promotion of performance of magnetorheological (MR) fluids, the researches for
application of these kinds of fluids have attracted much attention. To get a further
understanding of how the MR fluids respond in the presence of a magnetic field, to
provide a direction to which leads the application of these fluids in the field of civil
engineering, and to enter the research realm of mesoscopic scale, we will adopt the
mesoscopic concept to deal with the mechanics of MR fluids.
MR fluids have a close resemblance with liquid crystals and superconductors in
that they all possess internal microstructures. Superconductors have been studied
on the mesoscopic scale whose representations include the surface, small scale, and
macroscopic quantum effects. MR fluids and liquid crystals can also be analyzed
by the mesoscopic approach. It is well known that the different macroscopic
theories of liquid crystals can be deduced from the mesoscopic theory. Therefore,
we can expand the development of macroscopic theories and find the mechanical
base of macroscopic approach by the use of mesoscopic concept.
Constructing the bridge between the microscopic and macroscopic theories is a
long-term goal for researchers. The three scales of studies in MR fluids can serve as
a paradigm of studying new sorts of materials and as a tool of understanding the
operations of mechanics system. We expect that this research will provide related
science and the engineering realm with useful information and thoughts and with a
further way for advance studies.
