Macroscopic Theories Of Matter And Fields A Thermodynamic Approach ( Advances in Science and Technology in the USSR)
Advances in Science and Technology in the USSR
Mathematics and Mechanics Series
This is a collection of articles by Soviet scientists on current issues of building macroscopic models of matter and fields. Based on thermodynamics concepts the papers develop general variational techniques of modeling material continuous media and fields allowing for their interactions in reversible and irreversible processes. The book is intended for researchers, engineers, graduate and postgraduate students interested in the mechanics of continuous media.
