Abstract: The paper derives the calculation formula ofmechanical constants for rubber under large elastic deformations based on energy theory. A set of experimental device has been made. The experiment and analysis have been conducted using two methods and the effects of time and delay have been included. The experimental method is available and the experimental results are satisfactory.

Key words: dual direction extention ratio, large extention with restrict in one direction, primary rubber deformation
