Abstract: | Summary This paper deals with the stationary heat conduction in a solid consisting of planar, isotropic or transversely isotropic
layers. The following cases are considered: (1) arbitrarily layered solid, (2) macroperiodically layered solid, consisting
of equal pairs of different basic layers with finite thicknesses, (3) microperiodically layered solid, consisting of equal
layer groups of two or more different basic layers of infinitesimal thicknesses. Assuming a perfect contact between the layers,
exact solutions for the plane, the axisymmetric and the general three-dimensional problem of macro- and microperiodically
layered semispaces, respectively, are derived using integral transforms and the transfer-matrix method. It is proved that
the microperiodically layered solid with isotropic or transversely isotropic basic layers is equivalent to a homogeneous transversely
isotropic solid.
