Shear Modulus Calculator

Estimate shear rigidity using four flexible input methods. Automatic unit conversion keeps your numbers consistent. Download a report, then compare with sample materials below.

Calculator

Choose the data you already have.
Result unit preference.
Affects on-screen inputs and notes.
Common engineering units: MPa, GPa, psi.
Dimensionless. Use small values for elastic range.
Used to compute shear stress: tau = F/A.
Cross-sectional area resisting the shear force.
Used to compute strain: gamma = delta x / L.
Distance over which displacement occurs.
Shear modulus: G = E / (2(1+nu)).
Typical range: 0.2 to 0.35 for many metals.
Tip: Use consistent geometry and loading assumptions. This tool assumes linear elastic behavior.

Formula used

Primary definition
G = tau / gamma
G is shear modulus, tau is shear stress, gamma is shear strain.
Helpful relationships
  • tau = F / A (force over area)
  • gamma = delta x / L (displacement over length)
  • G = E / (2(1+nu)) (from material constants)
Units: stress and modulus share the same dimensions (pressure).

Example data table

Material Typical shear modulus Notes
Steel ~79 GPa Strong, stiff; widely used for structural parts.
Aluminum ~26 GPa Lighter than steel; lower shear rigidity.
Copper ~44 GPa Ductile and conductive; moderate rigidity.
Glass ~30 GPa Brittle; properties depend on composition.
Rubber (soft) ~0.0003 to 0.001 GPa Very low modulus; large strains are common.
Values are approximate and vary with grade, temperature, and processing.
