Contact strength of two elastic half-spaces with a circular recess
The paper presents the analysis of the stress-and-strain state of a contacting couple consisting of two isotropic semi-infinite solids one of which has a small surface recess. Based on the classical criteria of fracture, namely the criterion of maximal principle stresses and criterion of maximal she...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Резюме: | The paper presents the analysis of the stress-and-strain state of a contacting couple consisting of two isotropic semi-infinite solids one of which has a small surface recess. Based on the classical criteria of fracture, namely the criterion of maximal principle stresses and criterion of maximal shear stresses, the regions of the most possible crack initial and plastic zones formation have been found. The brittle cracking can be induced by both tensile and compressive stresses arising at the interface. For some shape of the recess, considered as an example, the analysis reveals that the fracture starts from the contacting solids boundary. |
