Abstract
A method is developed to determine the initial spatial distribution T-0(x) of the temperature field in the central layer of a body from temperature me asurement histories recorded in both side layers of the same body. The reso lution of this inverse heat conduction problem is based on the minimization of a L-S criterion by using conjugate gradient algorithms. The practical c ase involving non perfect thermal conditions between the layers is analyzed .
