Applied Physics and Mathematics Annotation << Back NONSTATIONARY THERMAL CONDUCTIVITY OF AN ISOTROPIC RECTANGULAR PLATE WITH PIECEWISE NONSMOOTH BOUNDARY CONDITIONS OF THE FIRST KIND YU.YU. GROMOV, A.V. RYAZHSKIKH, V.I. RYAZHSKIKH An analytical solution of the problem of heat propagation in a rectangular plate with piecewise-smooth boundary consequences of the first kind is obtained by jointly applying the Fourier and Lasplace integral transformations. The computational experiment demonstrated the dynamics of temperature fields. Keywords: heat equation, boundary conditions of the first kind, rectangular plate.
