The method continuously gives the stress to the testpiece by rotating the screw shaft. The apparatus comprises a mounting plate for mounting the sample cell or the testpiece; a probe for compressing the cell load in touch with the testpiece; LVDT (linear variable differential transformer) connected with an amplifier for transforming the displacement to the voltage; a frame for fixing the cell load on the lower side and fixing the load cell on the upper side; a movable means for giving the vertical stress on the upper side of the load cell.
