Interatomic forces developed by thermal agitation do not obey Hooke's law. Consequehtly, by oscillating, the atoms exert on one another repulsive forces which are sensibly constant over a period of time. Therm alstrains which two parts of a crystal exert on each other are equal to the résultants, referred to unit area, of the repulsive forces exerted by the atoms of one part upon the atoms of the other part. By this definition, it is possible to estimate the thermal tensions as a function of the temperature and of the fundamental properties of the crystalline medium : its potential energy and its elementary translations. We find that, at low and intermediate temperatures, thermal tensions are proportional to the squares of the average quadr...
