Abstract: This work proposed a technique reference on the determination of autofrettage pressure for ultra-high pressure valve. The detailed numerical autofrettage process for a valve body with 340 MPa design pressure was established, where material’s Bauschinger effect was considered by a Chaboche kinematic hardening model. Validating autofrettage test was conducted at 600 MPa and 650 MPa hydraulic pressure. The effectiveness of autofrettage result was verified by the surface strain consistency with numerical calculation as well as the existence of plastic strain unraveled by electron backscatter diffraction (EBSD) characterization.
