Foreword
Eshelbian mechanics of materials
Among the many specialized minisymposia organized during the ASME 2001 Mechanics and Materials Summer Conference held in San Diego, CA, 27–29 June, 2001, one was devoted to the ‘‘Eshelbian Mechanics of Materials’’. By this one understands the mechanics of material continua projected entirely on the material manifold; the main kinetic ingredient then becomes the energy–momentum tensor introduced by Eshelby in 1951, a stress tensor now more properly called the Eshelby material stress tensor. The accompanying thermomechanics then is none other than the thermomechanics of driving––or configurational––forces acting on field singularities, defects, and structural rearrangements of matter. This includes driving forces on dislocations, cracks, phase-transition fronts and shock waves, and thermodynamical forces governing wear, delamination, growth, and anelasticity. Sixteeen invited contributions were delivered at this minisymposium with a balanced participation of scientists from the USA and outside. Twelve of these contributions are reproduced here in written form after the usual refereeing procedure and in the usual format of MRC. The reader will be happily surprised by the unity that transpires from these although several ‘‘schools’’ of thought are already at work in such a potentially rich field of research. G.A.
