Abstract: 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.

Abstract: A shape memory effect measuring apparatus useful for tensile stress, strain and recovery stress measurement comprising a load cell, LVDT (Linear variable displacement transducer), temperature sensor, rigid platform, a PC based data recorder and processing system developed for load cell, temperature sensor, load frame, grips to hold sample and a liquid bath. The instrument has the provision of sample testing in the controlled uniform temperature and defined liquid environment. The liquid bath is mounted on the rigid stand platform to hold the liquid bath. Sample and holding grips are submerged in the liquid. A uniform temperature of liquid is attained by controlled heating and stirring arrangement. A PC based controller is used to monitor and control the desired temperature of the sample. The holding device is used to fasten a specimen by the suitable grips.
