摘　　要：This paper investigates the frictional thermoelastic contact of a rigid spherical punch and functionally graded material(FGM)coated half-space with arbitrarily varying material properties.These material parameters include the elastic modulus,Poisson’s ratio,heat conduction parameter,and thermal expansion coefficient.The material parameters of the FGM coating and half-space are assumed to be temperature dependent.The spherical punch is rotated in the FGM-coated half-space at a constant angular speed.The generated frictional heat is related to the friction coefficient,contact radius,angular velocity,and contact pressure.A theoretical formula for the thermoelastic rotating contact problem is established and solved using the finite element method.The main objective of this paper is to investigate the effects of temperature dependence,gradient index,friction coefficient,angular velocity,and gradient form on the surface temperature and stresses.
