摘要：In this paper the creep parameters for a Norton law material are determined from the creep bending tests data by an elliptical arc shape specimen. According to the ideal time-dependent beam theory, the creep coefficient B and creep exponent are derived as a function of the applied load and displacement rate. Finite element simulations of the elliptical arc specimen bending creep are also carried out to validate the feasibility and accuracy of the proposed approach. Our work will contribute to a better understanding to derive creep parameters from creep bending test and extend its application for the milli/micro scale miniature specimen. (C) 2013 Elsevier Ltd.
