Abstract

We propose a new optical method for the determination of the rigidity modulus G of solid materials. With this method, the rigidity modulus is determined by measuring of the twisted angle (theta) of the material, depending on an applied force. The measuring of this twisted angle is obtained by using an ultra sensitive polarimetric sensor. The effective measurement of rigidity modulus G for Aluminum and Plexiglas are experimentally achieved, we obtained respectively 1,44464.10¹⁰N/m² and 0,99417.10⁹N/m².
