Abstract
An experimental investigation of the variation in Poisson's ratio during elastic-plastic transition of a mild steel is presented. It emphasizes the relation of deformation induced thermal events to mechanical events of design interest and demonstrates the applicability of coupled thermomechanics as a means of evolving meaningful criteria on materials behavior. The foundation of coupled thermoelastic theory are derived from concepts encountered in irreversible thermodynamics. It is shown that these foundations provide a means for mathematically describing a physically meaningful criterion for uniaxial yield of ductile materials. Moreover, the experimental results provide sufficient evidence to establish the validity of the derived criterion for the specific material tested.
