NUMERICAL CALCULATION FOR THE FIRST KIND STRESS INTENSITY COEFFICIENTS FOR THE CRACK IN THE HALF-SPACE ^{[№ 5 ' 2009]}
The article addresses determination of coefficients for the first kind stress intensity for the crack that is situated under control angle towards the half-space. It defines the dependence of the first kind stress intensity coefficients on the angle between the crack and half-space. Adequacy of the modeling results was confirmed with their comparison with the results made by the other authors.
