Abstract
An inverse analysis is used to estimate linearly temperature dependent thermal conductivity components k(x)(T), k(y)(T) and specific heat ca pacity C(T) per unit volume for an orthotropic solid. Simulated measur ed transient temperature data are generated by adding random errors to the exact temperatures computed from the solution of the two-dimensio nal, direct transient heat conduction problem. An iterative procedure, based on minimizing a sum of squares function with the Levenberg-Marq uardt iterative procedure is used to solve the inverse problem.
