Definition

The linear-elastic material constant G (modulus of rigidity) defined as the ratio of shear (tangential) stress to engineering shear strain within the material's elastic regime (τ = G·γ); units: pascal (Pa).

Definition

An elastic material constant that quantifies the linear proportionality between shear stress (τ) and shear strain (γ) in the small‑strain, reversible regime; commonly denoted G and expressed by τ = G·γ for isotropic, linear elastic materials.
