Abstract
In this chapter, we consider theory of thermal stresses based on the space-time fractional heat conduction equation with the Caputo fractional derivative with respect to time describing time-nonlocality and the fractional Laplace operator (Riesz operator) with respect to spatial variables describing space-nonlocality. Fundamental solutions to the Cauchy and source problems for axisymmetric equation in polar coordinates and central symmetric equation in spherical coordinates are obtained using the integral transform technique. Numerical results are illustrated graphically for different values of order of time- and space-fractional derivatives.
Always listen to experts. They’ll tell you
what can’t be done, and why. Then do it.
