| Abstract: | The mechanical properties of the typical combined fittings with a long radius and double elbows in the combined fittings of pressure pipes under the action of internal pressure were studied using finite element method because the estimated formula of plastic limit load of existing fittings was not suitable for combined fittings,and the engineering estimated formula of plastic limited internal pressure of combined fittings with a long radius and double elbows was fitted through the calculated results. |
