Calculation method of limiting plastic strains in the angular concentrator zone

Abstract

The approach to determination of plastic strains near tip of angular notch is considered by the example of problems of the uniaxi al a stretching of cylindrical and flat samples with angular notches. At calculation we propose, that the sample body is compound: the material is elastic-plastic as a whole, but we propose that the material is rigid-plastic in small area near critical point (the tip of the notch). This assumption allows realizing the numerical-analytical approach to determination of strain fields.
