The development of contact and noncontact technique to study the heat dissipation in metals under loading

Abstract

This work is devoted to the development of experimental technique allowing the analysis of energy balance in metal specimens during mechanical test and construction of heat sources field. The use of infrared thermography (IRT) is connected primarily with problem of definition of the time constant related to the heat losses. The goal of this work is to develop the technique which allows avoiding the additional experiments consisting in cooling test to find heat losses constant. Proposed technique is a combination of contact (heat flux sensor) and noncontact (IR camera) equipment which could be used during mechanical test.
