Identification of heat source fields from infra-red thermography: Determination of ‘self-heating' in a dual-phase steel by using a dog bone sample

Abstract : From infra-red thermography, a quantitative analysis of heat dissipation sources is proposed via the thermomechanical modeling of a fatigue test on a specimen with a varying cross-section. A new procedure is introduced to achieve this goal, and its application to an experimental case of self-heating at a single load level is shown to provide complete identification of a probabilistic model of micro-plasticity.
