How can I measure the shear modulus from a small specimen (metal & single crystal)?
There are some techniques applicable to small samples that do not measure shear modulus directly, but you can obtain elastic stiffness coefficients with them and then calculate the shear modulus:
-ultrasound spectroscopy
-Brillouin spectroscopy
-Inelastic Neutron (cm samples) or X-ray (µm samples) scattering
Hello Michał Stękiel, could you tell me how to calculate the shear modulus with the known elastic stiffness? Thank you so much!!!
You can measure deformations in the longitudinal directions and transversale direction.et in principal directions inclined by 45 ° using gauges. Then with the help of mohr circle Relations on deformations and of the stresses you can estimate the shear modulus G
