Test for determination of Shear Modulus

Conditioning load : Bearings shall be preloaded with maximum horizontal load Htest (with Ntest or vertical load held constant) and unloaded before test loading.
Rate of loading : Ntest corresponding to σm = 5 MPa shall be held constant during test and the horizontal loading H shall be gradually increased to yield a shear stress rate of approximately 0.05 to 0.1 MPa per minute.
Maximum test loading Ntest : The horizontal loading H shall be increased upto a maximum Htest which corresponds to horizontal deflection equal to 'h' (total elastomer thickness).
Measurement : Load and deflection measurements shall be calculated at approximately equal intervals not less than 5.
