Аннотация

The problem of the three-dimensional nonstationary temperature field of a sample of material when a thermal pulse of short duration acts on its surface is solved numerically. The scales of the errors in determining the thermal characteristics of the material by a pulse method due to the assumption that heat transfer in the sample is a one-dimensional process, is estimated. The limits of the ranges of possible variation of the ratio of the area of the heated surface of the sample and the zone of thermal heating, which ensure minimum errors in determining the thermal characteristics, are established.
