Moving Heat Sources in a Half Space: Effect of Source Geometry
نویسندگان
چکیده
Stationary and moving plane heat source analysis have application in several manufacturing processes such as metal cutting, spot welding, laser cutting/surface treatment (using CO2 or Argon lasers) as well as tribological applications including ball bearing and gear design [1-5]. Temperature profile and the rate of cooling at and near the surface can affect the metallurgical microstructures, thermal shrinkage, thermal cracking, hardness distribution, residual stresses and heat affected zones of the material [6]. Knowing temperature distribution in tribological applications due to frictional heat generation is required to minimize thermal related problems such as lubricant break down [7].

Quasi-Static Deformation of a Uniform Thermoelastic Half –Space Due to Seismic Sources and Heat Source
This paper investigates the quasi-static plane deformation of an isotropic thermoelastic half-space due to buried seismic sources and heat source. Governing equations of thermo-elasticity are solved to obtain solutions for seismic sources in a thermoelastic half-space. The general solutions are acquired with the aid of Laplace and Fourier transforms and with the use of boundary conditions. The ...
