Opis:: An analytical solution of a 3D transversely isotropic thermoelastic problem of a uniform heat flow disturbed by a penny-shaped rigid sheet-like inclusion (anticrack) with some small conductivity is obtained by using the potential theory method. The behaviour of thermal stresses near the edge of the disc is analysed from the standpoint of the mechanics of fracture initiation.

Tematy:: heat flux
three parallel cracks
stress intensity factor
infinite orthotropic plane
Opis:: Two upper collinear cracks are placed parallel to a lower crack in an infinite orthotropic plane under uniform heat flux perpendicular to the cracks. The surfaces of the cracks are assumed to be thermally insulated. The mixed boundary value conditions with respect to the temperature field and those with respect to the stress field are reduced to dual integral equations using the Fourier transform technique. In order to satisfy the boundary conditions outside the cracks, the differences in temperature and displacement at each crack surface are expanded in a series of functions that are zero outside the cracks. The unknown coefficients in each series are evaluated using the Schmidt method. The stress intensity factors are then calculated numerically for selected crack configurations.

Tematy:: MHD

Opis:: A study of magnetohydrodynamic (MHD) flow with viscous dissipation and heat transfer in an electrically conducting laminar steady viscous incompressible micropolar fluid between two infinite uniformly stretching disks is presented. The transformed self similar nonlinear ODEs are first linearized using a quasi linearization method and then solved by employing a combination of a direct and an iterative method. The study may be beneficial to flow and thermal control of polymeric processing.

Tematy:: channel flow
shrinking/stationary walls

Joule heating
viscous dissipation
Opis:: We present the numerical study of hydromagnetic (MHD) flow and heat transfer characte- ristics of a viscous incompressible electrically conducting micropolar fluid in a channel with one wall shrinking and the other at rest in the presence of a transverse applied magnetic field. Different from the classical shooting methodology, we employ a combination of a di- rect and an iterative method (SOR with optimal relaxation parameter) for solving the sparse systems of linear algebraic equations arising from the FD discretization of the linearized self similar nonlinear ODEs. Effects of some physical parameters on the flow and heat transfer are discussed and presented through tables and graphs. The present investigation may be beneficial to the flow and thermal control of polymeric processing.
