如何计算Shear Modulus
learn.whatIsHeading
Shear modulus (G) measures resistance to shear deformation: G = shear stress / shear strain; related to stiffness.
公式
Calculate G = τ/γ
- G
- τ/γ — τ/γ
分步指南
- 1Input shear stress and shear strain or material properties
- 2Calculate G = τ/γ
- 3Results show shear stiffness
例题解析
输入
Steel: G ≈ 80 GPa
结果
Rubber: G ≈ 1 MPa (much softer in shear)
常见错误注意事项
- ✕Using wrong stress/strain definitions (must be shear)
- ✕Confusing with bending stiffness
常见问题
How do Young's and shear moduli relate?
G = E / (2(1+ν)) using Poisson's ratio.
