Metal Plasticity as a Problem of Thermodynamics

  • Joseph Kestin
Conference paper


The lecture presented at the Symposium was based on two recent papers [1, 2], each of them representing the text of an invited lecture.

There exists a well-developed empirical theory of plastic deformation in metals which allows engineers successfully to predict the behavior of a variety of structures and machine elements loaded beyond the elastic limit for purposes of design. This theory rests, essentially, on a number of ad hoc assumptions. Many attempts have been made to fit this phenomenon into the formalism of thermodynamics to provide for it a securer scientific basis. Much progress in this direction has already been made. However, none of the proposals advanced so far has met with general acceptance.
