The problem of stress concentration in elastic orthotropic and quasi-orthotropic bodies weakened by sharp and rounded V-notches under symmetrical load (mode I) was considered. Particular attention was paid to the method of unified approach to problems of stress distribution around such concentrators, according to which the stress intensity factors for sharp notches are calculated on the bases of stress concentration factor at the vertex of corresponding V-notch rounded with small radius of curvature. Using this approach, the notch stress intensity factors at V-shaped corner of two-sectional kinked crack in orthotropic and quasi-orthotropic plane were calculated. (C) 2016 Elsevier Ltd.
