In materials science, Schmid's law (also Schmid factor ) describes the slip plane and the slip direction of a stressed material, which can resolve the most shear stress. 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 … See more • Critical resolved shear stress See more • Translation into English: Schmid, Erich; Walter Boas (1950).
