The slab model study has been performed to provide quantitative data analysis in the case of presence of the influence of the thermal contact resistance effect solved by introducing the heat transfer coefficient in between the heat source and specimen body and the effect of the heat capacity of the heat source. Both of these effects influence the initial increase of the thermal response and subsequently its deformation. Finally, the initial thermal history in generation of the heat pulse and its transfer to the specimen influence development of the shape of temperature response. In theoretical background of this study we discuss the analysis of the model for temperature response function derived for the geometry of the infinitively large slabs having final thicknesses. The slab model accounts the heat capacity of the heat source as well as the heat transfer coefficient in between the heat source and the specimen body. The theoretical calculations of the thermal responses for different heat capacity of the real heat sources were done. The increasing heat capacity of the heat sources shifts the onset of the thermal response toward lower times. Similar effect was found for the increasing values of the heat transfer coefficients.
