The Transient Thermoelastic Contact of a Sphere Sliding on a Plane*
نویسنده
چکیده
A solution based on a Hertzian approximation to the contact pressure distribution is obtained for the transient thermoelastic contact of a sphere sliding on a rigid non-conducting plane. With this simplification an integral equation formulation is obtained. In a nondimensional form the only independent parameter is the starting condition and numerical results are presented for various values. An analytical solution is obtained for short values of time and shows that the contact radius falls linearly at a rate dependent only on the steady state contact radius and the thermal diffusivity of the sphere.

Thermoelastic Displacements and Stresses Due to a Heat Source Moving Over the Surface of a Half Plane
If two thermally conducting bodies are in sliding contact, the frictional heat generated at the interfaces causes thermoelastic distortion which profoundly influences the extent of the contact area and the distribution of contact stress [1]. This phenomenon now known as thermoelastic instability has been observed experimentally in a wide range of practical sliding systems [2, 3]. Several theore...
متن کاملInteraction of thermal contact resistance and frictional heating in thermoelastic instability
Thermoelastic contact problems can posess non-unique and/or unstable steady-state solutions if there is frictional heating or if there is a pressure-dependent thermal contact resistance at the interface. These two effects have been extensively studied in isolation, but their possible interaction has never been investigated. In this paper, we consider an idealized problem in which a thermoelasti...

This article is concerned with the theoretical analysis of the functionally graded magneto-electro-thermoelastic hollow sphere due to uniform surface heating. We analyze the transient thermoelastic problem for a functionally graded hollow sphere constructed of the spherical isotropic and linear magneto-electro-thermoelastic materials using a laminated composite mode as one of theoretical approx...
متن کاملStability of thermoelastic contact for a rectangular elastic block sliding against a rigid wall
In this note, we determine the stability boundary for the thermoelastic contact of a rectangular elastic block sliding against a rigid wall in the presence of a pressure-dependent thermal contact resistance. This geometry can be seen as intermediate between the idealized ‘Aldo’ rod model and continuum solutions for the elastic half-plane. The solution is obtained by comparing the expression for...

In this paper a closed form solution for one-dimensional magnetothermoelastic problem in a functionally graded material (FGM) hollow sphere placed in a uniform magnetic field and temperature field subjected to an internal pressure is obtained using the theory of magnetothermoelasticity. Hyper-geometric functions are employed to solve the governing equation. The material properties through the g...
