The uniaxial shear strain gauge is an element that changes its resistance when subjected to strain. The uniaxial shear strain gauge was developed specifically for the manufacture of precision force and torque transducers using the shear beam principle of operation.
Tips: What is shear strain gauge?
Shear strain means that in the case of simple shear, the material is subjected to a force F which is two forces of equal magnitude and opposite direction parallel to the cross section A0, and under this shear force, the material will be deflected. The tangent of the deflection angle θ is defined as the shear strain γ: i.e. γ = tanθ. When the shear strain is small enough, γ = θ and the corresponding shear stress is τ = F/S.
