... to further develop this pipe strain demand assessment by including variable effects of internal pressure and temperature of steel pipes buried in soils of different stiffness. The developed strain demand criterion considers inelastic material behaviour for different grades of steel pipe, as well as bi-linear...

... for Alloy 617. Experiments were designed and performed using internal pressurized tubular specimens at 950 °C on Alloy 617. The sustained primary-load was introduced by the internal pressure. A newly developed SMT technique, single-bar SMT, was extended to these tests and SMT creep-fatigue test data were...

... Abstract Ellipsoidal head is a common end closure of pressure vessel. Plastic collapse is a crucial failure mode considered in the design of ellipsoidal head subjected to internal pressure. Internally pressurized ellipsoidal head tends to be hemisphere (geometric strengthening) due...

... Abstract Based on the Hill yield criterion, the analytical solutions of the limit load of orthotropic thick-walled pipes under pure internal pressure, bending moment and torsion are given respectively. The simplified Mises analytical solution and finite element results of limit load...

... distributions on reinforced nozzle corners of pressure vessels under internal pressure. This method includes simplified equations for predicting stresses on the inner surfaces of the nozzle corner region. These equations are expressed in terms of stress concentration factor (SCF) and geometric variables...

... by steam or internal pressure can easily be estimated by a conventional FEM code. However estimation of system load caused by thermal expansion of pipe materials is difficult because of the complex structures of piping system. In this study, we developed a three-dimensional FEM code which can estimate both...

... Tests on two internally pressurized toroidal shells are described in the paper. These were laboratory scale models manufactured by welding 90°, 316L steel elbows. Outside diameter of toroids was about 310.0 mm, radius of the tube was about 41.0 mm and the wall thickness was about 3.0 mm...
