Statistics Filters
The Schmid factors are found using this Filter. The component of the axial force F that lies parallel to the slip direction is F cos λ. The resolved shear stress on the slip plane parallel to the slip direction is therefore given by:
resolved shear stress = (applied stress)(cos φ cos λ)
The angle φ is the angle between the tensile axis and the slip plane normal, and λ is the angle between the tensile axis and the slip direction in the slip plane.
It is found that the value of the resolved shear stress at which slip occurs in a given material with specified dislocation density and purity is a constant known as the critical resolved shear stress τ(Critical). This is Schmid's Law.
The quantity cos φ cos λ is called the Schmid factor. The tensile stress at which the crystal starts to slip is known as the yield stress σy, and corresponds to the quantity 'applied stress' in the above equation.
