A technique of material tailoring to achieve desired thermomechanical fields in hollow cylinders composed of functionally graded materials (FGMs) is presented in this paper. First, the desirable stress distribution and temperature field are prescribed. And then the required variations of the Young's modulus, the Poisson's ratio and the thermal expansion coefficient with the radius to achieve the corresponding state of stress and temperature distribution within FGMs cylinders are found. Different kinds of the required variations of the material constants with the radius to fulfill the same purpose are given for FGMs cylinders. The multi-optional variations of the material constants to achieve the same desired thermomechanical field presented here may be interesting and helpful to the design of the inhomogeneous material.
Keywords:Solid mechanics; material tailoring; functionally graded materials; hollow cylinder; desired thermomechanical fields
