[Show abstract][Hide abstract] ABSTRACT: We study the thermoelastic contact of two isotropic semiinfinite bodies with periodic system of grooves on the surface of one of these bodies in the presence of heat-permeable media in the intercontact gaps. We reduce the formulated contact problem to a system of nonlinear singular integrodifferential equations for the height of gaps and the jump of temperature between their surfaces, which is solved numerically. With regard for the directional effect of the heat flow, we analyze the influence of the thermomechanical load and thermal conductivity coefficient of the filler on the contact parameters of the analyzed system.

[Show abstract][Hide abstract] ABSTRACT: This paper provides a numerical verification that the singular term of Williams׳ series eigenexpansion can be used as a singular solution, valid in the neighborhood of each crack tip, in a single-region dual boundary element analysis of two-dimensional piece-wise flat multi-cracked plates, either with edge or internal cracks, in mixed-mode deformation, as an intermediate and necessary research step towards the implementation of the singularity subtraction technique.
