The effect of porosity gradient on the maximum tensile thermal stresses during transient heat flow for a circular cylinder is calculated using finite element method. It is shown that with appropriate porosity distribution the maximum tensile thermal stress in the cylinder is substantially reduced without the loss of strength in the critical region, thus improving the thermal stress resistance of the material.
