Abstract: Yield stress is an important indicator of the strength of a component such as a pipe section. A method and apparatus for measuring yield stress of components made from magnetic materials is provided. The magnetic permeability of the material is recorded at multiple stress levels below yield establishing a permeability-stress relationship. The yield stress is then estimated as a function of the recorded permeability-stress relationship.
