"WebbShear is movement of two portions of the crystal at an angle with respect to the tension directions, along a shear plane. Shear is more likely because atomic bonds do not need to be fully broken. Instead they can hop to their neighbors as shear progresses. Due to Polyani and Orowan, the theoretical cleavage stress is σ max ≈ E π " - Theoretical shear stress
