Yield Stress
Plastic deformation of aluminium requires a tensile stress that exceeds a critical stress σy, the yield stress. This stress corresponds to the stress that is necessary to push a dislocation through an arrangement of many other dislocations. A typical magnitude of σy for pure Aluminium is σ ≈ 1 MPa.
