Elastic-plastic states of two-layer curved bar under pure bending



Analytical solution of an elastic-partially plastic two-layer curved bar subjected to couples at both ends is obtained. The solution is based on Tresca's yield criterion and its associated flow rule. Numerical results for real engineering materials in partially plastic stress state are presented in graphical form. (© 2012 Wiley-VCH Verlag GmbH & Co. KGaA, Weinheim)
