Analyse thermographique des mécanismes de localisation dans des aciers doux
Using infrared image processing, the evolution of the heat source's distribution is determined on steel samples during monotone tension tests. We first show that one or more narrow and dissipative bands propagate along the gauge part of the sample during the plastic plateau that precedes the strain hardening. We then describe the progressive concentration of strong dissipation zones during the strain hardening, which prefigures the localized necking of the sample
