Abstract

In
this study, the stress analysis of the cylindrically curved beam, which is
functionally graded for thermal load in radial direction, has been analytically
analyzed. The temperature distribution varies steadily state as a function of
the radial coordinate. The beam is assumed to be in the plane strain state. The
elasticity modulus of the functionally graded beam is assumed to vary with the
power law in relation to the thickness of the beam. In addition, the effect of
the vary in the power law parameter and with the general mixture law, all
material properties of the beam  (modulus
of elasticity, density, thermal expansion coefficient, thermal conductivity
coefficient and yield stress) except for Poisson's ratio change in radial
direction. Thus, all material properties of the beam vary depending on the
power law. Beam; stresses under positive, negative and homogeneous temperatures
were examined. Stress analysis is considered according to Von Mises yield
criterion.
