Abstract: Residual stress of a welding joint based on finite element simulation was predicted to gain popularity in the process equipment industry. As for the nuclear power industry, the weldment located in a primary coolant system ...

Abstract: Excessive ratcheting deformation is a typical failure mode of pressurized pipeline under repeated loads in practice. There are still very few studies regarding the analytical ratcheting limits of pressurized pipes subjected ...

Abstract: The analytical pretightening force range of flange joints in a pipeline was deduced based on the allowable gasket stress and flange rotation angle considering the nonlinear compression resilience behavior of gaskets. ...
