| Abstract: |
The paper presents a new mathematical model for the solution of a static skew-symmetric boundary value problem for a layer weakened by two through holes with sliding sealing of its ends. A new method based on a system of six singular integral equations has been developed and tested numerically. As a result of a highprecision numerical study, it was found that with a decrease in the center-to-center distance or Poisson's ratio, an increase in the relative circumferential stress occurs. And with an increase in the Poisson's ratio, the maximum relative circumferential stress shifts from the bases of the layer to its depth. Under certain combinations of parameters, the effect of the presence of the second hole in the layer ceases to affect. The corresponding values are given. The paper presents the respective dependency graphs. [ABSTRACT FROM AUTHOR] |
