Shear modulus (G) measures resistance to shear deformation: G = shear stress / shear strain; related to stiffness.

Formel

Calculate G = τ/γ
G
τ/γ — τ/γ

Trin-for-trin guide

  1. 1Input shear stress and shear strain or material properties
  2. 2Calculate G = τ/γ
  3. 3Results show shear stiffness

Løste eksempler

Input
Steel: G ≈ 80 GPa
Resultat
Rubber: G ≈ 1 MPa (much softer in shear)

Almindelige fejl at undgå

  • Using wrong stress/strain definitions (must be shear)
  • Confusing with bending stiffness

Ofte stillede spørgsmål

How do Young's and shear moduli relate?

G = E / (2(1+ν)) using Poisson's ratio.
