The transverse shear modulus, often denoted as “G,” is a measure of a material’s resistance to shear deformation. It’s important in aircraft design, particularly when assessing the behavior of materials under different types of stress, including shear stress.
The formula for the transverse shear modulus (G) is related to the shear stress (τ) and the shear strain (γ) and is defined as:
- G is the transverse shear modulus, measured in pascals (Pa) or newtons per square meter (N/m²).
- τ (tau) is the shear stress applied to the material, measured in pascals (Pa).
- γ (gamma) is the shear strain, which represents the angular displacement or deformation in response to the shear stress (dimensionless).
