A method to estimate plastic loads for elbows with non-uniform thicknesses

ABSTRACT This paper provides a method to estimate plastic loads [defined by the twice‐elastic‐slope (TES)] for elbows with non‐uniform thicknesses under in‐plane bending and under internal pressure, based on systematic FE limit analyses using elastic‐perfectly plastic materials. The intrados thickne...
