Abstract
Worldwide, actual design standards allow for taking into consideration plastic deformations in order to achieve a higher degree of utilization. In this context maximum plastic strains, which can be allowed for tubular steel pipes exposed to internal pressure and additional loads, are of special interest. In this paper results of investigations on the elasto-plastic bearing behavior of steel pipelines subjected to internal pressure and bending are presented. Four-point bending tests on eight steel pipes on the model scale (D/t = 132) were carried out in order to investigate the buckling behavior in the elasto-plastic range. For the application on buried pipelines Finite-Element (FE)-models were checked by test results. Furthermore an analytical method based on the differential equation for beams with longitudinal tensile force and variable bending stiffness was developed, which is suitable to determine the elasto-plastic bearing capacity for internal pressure and bending. The collapse due to plastic shell buckling is taken into consideration by a limit criterion based on critical strains.
