[pdf] Configurational Forces as Basic Concepts of Continuum Physics: v. 137 Morton E. Gurtin

For the last decade, the author has been working to extend continuum mechanics to treat moving boundaries in materials focusing, in particular, on problems of metallurgy.
This monograph presents a rational treatment of the notion of configurational forces; it is an effort to promote a new viewpoint. Included is a presentation of configurational forces within a classical context and a discussion of their use in areas as diverse as phase transitions and fracture.
The work should be of interest to materials scientists, mechanicians, and mathematicians.
