Nucleation of cracks in a perforated fuel cell
V. M. Mirsalimov Azerbaidjan Technical University, Baku, AZ1129Azerbaidjan, USA
Abstract:
A mathematical model is constructed for crack nucleation in an isotropic fuel cell (heat-releasing solid material) attenuated by a biperiodic system of cooling cylindrical channels with a circular cross section. Cracks are assumed to appear with increasing heat-release intensity in the bulk of the material. The solution of the problem on equilibrium of an isotropic perforated fuel cell with crack nuclei reduces to the solution of a nonlinear singular integral equation with a Cauchy-type kernel. The solution of the latter equation yields the forces in the band of crack nucleation. The condition of crack nucleation is formulated with allowance for the criterion of ultimate extension of bonds in the material.
Keywords:
perforated heat-releasing material, pre-fracture zone, bonds between crack faces.
