摘要：
It is proposed to determine the scatter in a Wohler diagram by analyzing temperature changes induced by microplasticity. A unified framework is introduced to study both phenomena. The identification procedure is applied to a dual-phase steel. (C) 2004 Academie des sciences. Published by Elsevier SAS. All rights reserved.
