Nonlinear Modeling of Heat Distribution during a Concreting Beam, Using a Heating Electric Wire

Abstract:

In this article unlike existing linear models, a nonlinear differential model is used to describe the nonlinear heat distribution in a reinforced concrete beam using a heating wire. The results of experiments carried out under different heating modes are adequately described with good approximation by the analytical results obtained using the methods of group analysis of differential equations.
