Abstract A novel tensile-testing machine has been manufactured by which the true stress-strain relation of a transparent plastic film at different rates of strain can be obtained by an optical means. The stress can be measured by the deformation of a spring setup, parallel with the specimen. Both the strain of the specimen and the deformation of the spring are, at the same time, photographed by a cylindrical lens placed on a rotating drum which is synchronized with the rate of tension. Therefore, various thin plastic films can be actually applied to this tensile-testing machine by which the states of rheological flow and phenomena of rupture can be determined accurately.
