Abstract
The problem is analyzed of determining the extremal temperature fields in three-layer cylindric shells ensuring a relatively low level of temperature stress. It is shown that the optimal tempe rature fields, as well as the arising temperature stresses, depend strongly on mechanical characteristics of a shell. Solutions for this class of problems for single-layer isotropic shells considered before within the framework of the classical Kirchhoff-Love theory are given in [1, 2].
