The rigidity modulus refers to the change of shape produced by a tangential stress.
The rigidity modulus is also referred to as the shear modulus. To convert GPa to Pa multiply by 109.
Data are largely from references 1, 2, and 3. Data for lanthanides were taken from reference 4. Some other data is in reference 5.
