Abstract: | In this paper an analytical solution of the temperature of an opaque material containing two overlapping and parallel subsurface
cylinders, illuminated by a modulated light beam, is presented. The method is based on the expansion of plane and cylindrical
thermal waves in series of Bessel and Hankel functions. This model is addressed to the study of heat propagation in composite
materials with interconnection between inclusions, as is the case of inverse opals and fiber reinforced composites. Measurements
on calibrated samples using lock-in infrared thermography confirm the validity of the model. |
