Experimental Evaluation of Intensity Coefficient of Stresses Along Surface Crack

摘要

A method for the quantitative determination of intensity coefficient of stresses (CIS) along surface of a semi-eliptic crack is described. This method is based on equations obtained experimentally, which linked a shape of surface semi-eliptic crack with relative depth of it, and geometrical interpretation about developing of a surface crack. Results obtained are compared with analogous data that gives familiar formula for determination of CIS in bend of a flat sample. A quantitative convergence of two results is established.
