Microporomechanics

Luc Dormieux is a professor at the Ecole Nationale des Ponts et Chaussees, specialising in the mechanics of porous environments. In 2002 he edited a special issue of the Journal of Engineering Mechanics, and is about to publish (16/10/2005) a book joint-edited with Franz-Josef Ulm entitled "Applied Micromechanics of Porous Materials", to be part of Springer-Verlag's CISM International Centre for Mechanical Sciences Series.
 
Djimedo Kondo is a professor at the Lille University of Science and Technology, specialising in the mechanical reliability of materials and structures & geomechanics. He has authored over 20 journal papers.
 
Franz-Josef Ulm is an associate professor at the Massachusetts Institute of Technology. He specialises in the durability mechanics of engineering materials and structures, computational mechanics, bio-chemo-poromechanics, & high performance composite materials. He sits on the editorial board of the Journal of Engineering Mechanics. He has recently co-authored a book with Luc Dormieux (see above) and co-authored the 2 volume "Mechanics and Durability of Solids" with Olivier Coussy in 2001.

Microporomechanics encapsulates the study of the micromechanics of porous media. Porosity is the most prominent heterogeneous property of all natural and most engineered composite materials, and is key to the understanding and prediction of macroscopic materials behaviour. As new experimental techniques such as nanoindentation now provide unprecedented access to micromechanical properties and morphologies of materials, it becomes possible to trace these features from the nanoscale to the macroscale of day-to-day engineering applications, and predict transport properties, stiffness, strength and deformation behaviours within a consistent framework of microporomechanics.
* Authored by recognised leading experts in the field of microporomechanics
* Introduces high quality landmark research that proposes a new framework for the description of the behaviour of porous materials
* Composed of a logical and didactic build-up from fundamental concepts to state-of-the-art theory
* Synergises the disparate subject areas of poromechanics and micromechanics
* Includes a variety of original problem sets that provide a hands-on application of the homogenization theories to specific materials configuration
 
Microporomechanics provides a first introduction to the micromechanics of porous media, and offers an invaluable resource for academic and industrial research scientists and engineers. It will also appeal to graduate students in biomechanics and bioengineering, civil and environmental engineering, geophysics and geomechanics, materials science, and engineering related to petroleum and gas exploration.

Intended as a first introduction to the micromechanics of porous media, this book entitled Microporomechanics deals with the mechanics and physics of multiphase porous materials at nano and micro scales. It is composed of a logical and didactic build up from fundamental concepts to state of the art theories.
