Popis:	In this paper, initial stress measurement theory of micropolar elastic medium by stress release method is described. This measurement method uses the circular solid inclusion cell (SI-cell) as the strain sensor. And because of the SI-cell is regard as inclusion embedded in the micropolar elastic medium, measurement theory is derived by use of the solution of the elastic material with a inclusion problem through the correspondence principle between elasticity and couple stress elasticity. The characteristic of this measurement theory is that the radius of an over coring is finite. Several examples are shown by graphical representation and numerical results.
