NONSTATIONARY HEAT CONDUCTION OF THREE-DIMENSIONAL 
BODIES WITH UNEVEN INCLUSIONS

I. T. Denisyuk

UDC 536.2

A study is made of the nonstationary heat conduction of 
a three-dimensional body with an uneven inclusion mated with the matrix 
by an ideal thermal contact. Using thermal potential determined and 
studied on uneven surfaces, the problem has been reduced to an unconditionally 
solvable system of integral equations. The results have been illustrated 
with an example of sudden heating of a body with a circular conic 
inclusion.
