Rubber is widely utilized in industries. However, material properties vary significantly depending on recipe and mixing / curing conditions. When conducting researches on mechanics of rubbers such as deformation, fracture and tribology, mechanical properties of the material being used in the research should be always examined. This is actually troublesome and causes difficulties in sharing results between researchers. Technical Section (A-TS03-29) in Materials and Mechanics Division of JSME proposed to establish a standard specimen with simplifying recipe and production method in order to share and promote researches on mechanics of rubbers. A standard Styrene-butadiene rubber specimen was made under a simple and open recipe and production method. The specimen is distributed in the members of Technical Section and its material properties were measured. Some organizations carried out uniaxial tensile and viscoelastic tests, and the results are compared. Biaxial tensile test is also carried out to identify strain energy density function for rubber material constitutive model.
