Resumo

The conception of the pulse heating (the Hash) investigations of the thermal diffusivity of constructional elements is described. The presented method considerably extends the application of classical Parker's method [1]. For this purpouse transient temperature fields in geometricai models of a half space, infinite plate and a circular disc have been determinated by the analytical method. These models create the theoretical and methodical basis of the thermal diffusivity determination. The presented method has been verificated experimentally upon a half space, an infinite plate and a circular disc models wIth the use of a pulse laser.
