Abstract

This paper presents a temperature-based method for the determination of the size of elastoplastic zones. A mathematical model describing the one-dimensional thermal problem of the propagation of a plastic zone is developed enabling the use of nonadiabatic temperature measurements in this role. Validation of the model with numerically generated temperature data has shown the proposed method to yield both accurate and robust estimates for the elastoplastic boundary. An experimental application revealed the method to be efficacious and the estimates for the elastoplastic boundary to agree well with those obtained by finite element analysis.
