Mature theory，high precision，wide use，macro/micro residual stress can be tested Strict requirements on material surface，limited penetration，only can measure the superficial surface of the material，expensive equipment，large volume，not suitable for field testing Neutron diffraction method Can detect three-dimensional stress，high spatial resolution，large penetration depth Construction and operation costs are extremely high，neutron sources are required，radiation is high，and surface residual stress cannot be detected Ultrasonic method The equipment is portable，easy to operate and can measure residual stress on the surface and inside Due to the influence of material microstructure，the measurement accuracy is low，and only the average stress along the measurement path can be obtained Magnetic detection method High sensitivity，large detection depth Only applicable to ferromagnetic materials，will produce magnetic pollution Nanoindentation method Small area detection can be realized The theory is not mature and the residual stress results of different models differ greatly Embedded sensor method Full cycle on-line monitoring of composite/additive manufacturing components can be realized It is only applicable to some composite materials and additive manufacturing materials，and will affect the original mechanical properties of materials
