Abstract
Thermal inspection of quadripartite objects is considered and an algorithm of the solution of this three-dimensional transient problem is described. The algorithm has been written in the PL/1 language for a series ES computer and in FORTRAN for a model SDS-7600 computer. Results of numerical calculations are shown pertaining to all the basic precedures of inspection o for materials with a thermal conductivity within the 0. 2-100 W/m. degree K range, with either linear or nonlinear boundary conditions. The dependence of the absolute temperature drop, the contrast, and the optimum time lags on the boundary conditions and on the parameters of the material, the defect, and the bonding-layer, and also on the heating rate and the geometrical parameters of the heating zone are discussed.
