Classical shakedown theorems and their extensions to various material models rest on the temperature‐independent coefficients. In this paper, the lower‐bound of direct methods is extended to the application on the heterogeneous materials with temperature dependent yield strength and elastic modulus. Moreover, a numerical platform is developed, which makes the practical application more convenient and efficient. (© 2014 Wiley‐VCH Verlag GmbH & Co. KGaA, Weinheim)
