Timoshenko Institute of Mechanics, National Academy of Sciences of Ukraine, Kyiv aut Two-parameter failure criterion for elastoplastic bodies with mode I cracks [Elektronische Daten] [G. Galatenko] The generalized Dugdale crack model is used to formulate two-parameter failure criteria for the cases of quasibrittle state and developed plastic zones at a mode I crack tip. The failure criteria relate the fracture strength characteristics and the stress mode at the crack tip through the plastic constraint factor. The critical state of bodies with cracks under uni-and biaxial loading is analyzed in the cases of plane stress and plane strain using the Tresca and von Mises yield criteria. A small-scale yield criterion, which is an analytic relation between the critical stress intensity factor and T-stresses, is established Springer Science+Business Media, Inc., 2007 crack nationallicence plastic constraint factor nationallicence developed plastic zone nationallicence two-parameter failure criterion nationallicence International Applied Mechanics Springer US 43/7(2007-07-01), 745-753 1063-7095 43:7<745 2007 43 10778 https://doi.org/10.1007/s10778-007-0073-z text/html Onlinezugriff via DOI 1 research-article jats NATIONALLICENCE 856 40 https://doi.org/10.1007/s10778-007-0073-z text/html Onlinezugriff via DOI NATIONALLICENCE 100 1- Galatenko G.
