Abstract: The paper examines the nonlinear elastic-plastic response of internally pressurized 90 deg pipe elbows under in-plane and out-of-plane bending. Nonlinear shell elements from a general-purpose finite ...

Abstract: The paper investigates the response of elbows under in-plane bending and pressure, through nonlinear finite element tools, supported by experimental results from real-scale tests. The finite element ...

Abstract: Mechanical damage in steel pipelines in the form of local buckles due to excessive bending deformation may severely threaten their structural integrity. The present paper describes experimental ...
