Yves Jorand

See "Grindosonic". Easy and rapid method.

Frank Kern

Hi Sohrab,

the appropriate method depends on the size and shape of your specimen.

1 The "classical" method is an instrumented bending test, however to correctly determine the elastic modulus you must measure the deflection properly, and you must prepare bars with rectangular shape.

2 for relativele thin plates and disks (r/d > 5) the acoustic method as proposed by Yves is suitable.

3 for small specimen instrumented microindentation can be used, calculates the modulus from the slope of the unloading curve.

best regards

Frank
