θ -Differencing Method for testing the Isolating Qualification of Some Materials

Abstract

   In this paper we use θ-differencing numerical method to account the time for heat diffusion through  the body of some materials, this method depends on three techniques or three roots according to the value of  θ :   Explicit Method,  Implicit Method, and  Crank-Nicolson (C-N) method. We obtain a results from these methods and we compare between them.
