Abstract: This paper proposes a ring element for the stress analysis of mitred bends, which is an extension of ring elements for pipe bends proposed by the present authors. Since accurate treatments ...

Abstract: The present paper describes a simplified finite element method for analysis of behavior of complex piping systems under elevated temperature. Elastic-plastic-creep deformations of a piping system ...

Abstract: The present paper investigates the flexibility and stress factors for the pipe bends when they are connected with straight pipes and subjected to out-of-plane as well as in-plane bending moments, ...

Abstract: This paper proposes a new finite element method for treating the stress analysis of a piping system under general loading conditions. This finite element method will be referred as the finite ...

Abstract: The creep behaviors of pipe bends under in-plane bending are studied by the use of the simplified ring element method. The typical two loading cases are studied; (a) constant in-plane moment, ...

Abstract: Geothermal energy extraction from hot, dry rock requires the circulation of water under pressure through a crack with a small opening (several millimeters) and a large radius (several hundred ...
