Abstract: Consideration of a geometrical nonlinearity is a common practice for thin-walled pressurized structures, especially when their cross section is not a perfectly circular one due to either initial imperfections or distortions ...

Abstract: A physically and statistically based method for steam generator (SG) heat exchanger tubes (HET) integrity assessment is proposed. The method based is on the stochastic laws of crack dimensions distribution with taking into ...

Abstract: Numerical procedures for calculation of reference stresses for pipelines with circumferential defects, based on simulation of global and local ultimate plastic states, are proposed. There are some peculiarities of proposed ...

Abstract: The paper is devoted to elaboration of the analytical O-procedure for the limit load analysis of complex shaped axial defect in a pressurized pipe. It is based on the classical lower bound theorem of the theory of plasticity, ...

Abstract: Based on the previous limit load analytical modeling for cracked thinwalled pipe (Orynyak, I. V., 2006, “Leak and Break Models of Pressurized Pipe With Axial Defects,â€‌ Proceedings of the 6th International Pipeline ...
