Engineering Shear Strain
Shear strain measures the angular distortion of a material under a shearing load. It’s defined as the ratio of lateral displacement to the original height perpendicular to that displacement: γ = Δx / h, which for small angles equals tan(θ), where θ is the shear angle.
Shear strain is dimensionless (it’s a ratio, not a length), and is directly related to shear stress through the material’s shear modulus (τ = Gγ). It’s a fundamental quantity in analyzing torsion, punching, and sliding-type deformation.
