Comparison of stability criteria of V-notched body under combined mode of loading

Abstract eng:
The stability criteria of V-notched bodies under combination of loading modes I and II are suggested and compared in the article. Methodology of stability criterion suggestion is based on analogy between behaviour of body with a crack and with a V-notch. Analytical approach to suggestion of stability criteria and methods of numerical estimation of magnitudes controlling stability of the concentrators are shown in the article. Corresponding evaluations are obtained from finite element method system ANSYS. Suggested criteria are mutually compared.
