ABSTRACT: A summary of previous work is first presented. Then an axisymmetric model is presented in which the bending of an infinite straight or curved pipe with external or internal pressure is simulated by thermal loading. The model includes geometric and material nonlinearity in the prebuckling analysis and bifurcation buckling from the nonlinear prebuckled state. Comparisons with tests on straight pipes and elbows are given. The calculations are performed with use of a slightly modified version of the BOSOR5 computer program. Qualitative agreement with test results is demonstrated.
