By using tensile test.
Brass is an alloy and as such can very greatly in its properties depending on its content, so there is no single shear modulus for brass. The only way to be certain is to either test it your self or go by data provided by the manufacturer. If, on the other hand, you are only working theoretically 40GPa is a good estimate for brass in general. Source: http://www.engineeringtoolbox.com/modulus-rigidity-d_946.html
Triaxial testing will yield static strength properties of the material while ultrasonic measurements will give dynamic strength properties. The two can be related to each other by using various relationships between Young's Modulus, Bulk Modulus, Shear Modulus and Poisson's ratio. Static results should be lower than the dynamic results.
how use the result of vane shear test
Yes, indeed. Sometimes tensile modulus is different from flexural modulus, especially for composites. But tensile modulus and elastic modulus and Young's modulus are equivalent terms.
