Abstract
PURPOSE:To determine the work strain on the basis of the base line levels before and after measurement by raising the temperature of a test piece from the room temperature, then reducing the temperature and continuously measuring the dimensional variation of the test piece. CONSTITUTION:The test piece is prepared by cutting out a cylinder of 4mm. in diameter and 3.5mm. in thickness from a bridge formation polyethylene molded article. The test piece is heated by means of a thermol machanical analyzer from the room temperature up to 130 deg.C at a heating rate 5 deg.C/min, then cooled at a cooling rate of 5 deg.C/min. During the heating and the cooling, the variation of the thickness of the test piece is mesured in accordance with the compression loading method to obtain a thermomechanical curve as shown in the drawing. The difference between the levels before and after heating, respectively, of the base line is determined from the curve. The curve indicates that the residual strain after machining corresponds to an expansion of 160mu, which corresponds to 4.6% of the entire test piece.
