WebApr 5, 2024 · Schmid’s Law : states that the critically resolved shear stress (τ) is equal to the stress applied to the material (σ) multiplied by the cosine of the angle with the vector normal to the glide plane (Φ) and the cosine of the angle with the glide direction (λ). The applied force along the tensile axis is F = σA.
