shear modulus - Typical values, Explanation


A measure of a material's resistance to twisting; symbol G, units Pa (pascal); also called the modulus of rigidity or torsion modulus. A higher G value means that the material is harder to twist. It is defined as shear stress divided by shear strain, and is applicable only to solids. For example, for steel G = 0·8 × 1011Pa.
