THERMOELASTIC STATE OF A SPHERICAL VESSEL FORMED OF FUNCTIONALLY GRADED MATERIALS

In present study, a generalized analysis of stresses for thermal in a functionally graded hollow
sphere is explored in steady-state. The thermal and elastic parameters are presumed to
randomly fluctuate along the radius of the hollow sphere with radial non-homogeneity. A
“Fredholm integral equation” is used to solve the boundary value problem related to a
thermoelastic issue. By resolving the resulting equation (the Fredholm Integral equation), we
may numerically determine the distribution of radial displacement and thermal stresses. The
effect of the material parameters' gradient fluctuation on stresses for thermal is examined, and
the numerical outcomes are visually displayed.
