Continuum with defect and self-rotation fields

Teisseyre R.

Vol. 50, nr 1

51-68

An elastic continuum containing dense distribution of internal nuclei (dislocations, disclinations, vacancies, thermal nuclei, or electric nuclei) are the objects/sources creating internal stresses (self stresses). We consider the rotation and twist fields and the internal nuclei generating these fields; in general an asymmetry of some fields shall be taken into account. We present total, self and elastic fields and the related compatibility conditions; the stress-defect density relations arc derived, proving the validity of our approach. The examples of experimental results are given to indicate the possibilities of recording the rotation and twist effects.
