Investigation of Relationship of Stress Intensity Coeficients in the Vicinity of Normal Tensile Cracks in the Form of Regular Polygons

摘要

The method of stress intensity coefficients determination in the vicinity of olain cracks in the form of regular polygon which is based on the representation of round crack's field is suggested. The formula obtained to determine the mentioned coeficients does not demand an explicit expression for the function of reverse transformation. It is shown that if the number of the polygon angles is more than six the crack form can be taken as circular when determining the mentioned coefficients.
