A shape memory effect measuring apparatus is provided that is useful for tensile stress, strain and recovery stress measurement. The apparatus includes a load cell, a linear variable displacement transducer, a temperature sensor, a rigid platform, a computer-based data recorder and a processing system a load frame, grips to hold sample, and a liquid bath. The liquid bath is mounted on the rigid stand platform to hold the liquid bath. A uniform temperature of liquid is attained by controlled heating and stirring arrangement. The computer-based processing system may be used to monitor and control the desired temperature of the sample. A change in length of a specimen and stress generated during expansion thereof may be recorded, from which strain and stress may be calculated using the apparatus.
