Theoretical shear strength
Webb29 jan. 2013 · This work demonstrates a simple but efficient way as to how to determine the existence of shear instabilities in ideal bcc crystals under uniaxial loading. The theoretical tensile strengths are derived from calculated values of the theoretical shear strength and their dependence on the superimposed normal stress. The presented … WebbThe theoretical shear strength was evaluated by Frenkel (1926). [19] where ds is the atomic distance along the slipping direction, dm is the distance between the row of atoms, and G is the shear modulus. As for the (111) plane of silicon, the theoretical shear strength becomes 13.7 GPa.

WebbIn engineering, shear strength is the strength of a material or component against the type of yield or structural failure where the material or component fails in shear. A shear load is a force that tends to produce a sliding failure on a material along a plane that is parallel to the direction of the force.
