Contact strength of two elastic half spaces with circular groove

B. Monastyrs’kyi , Andrzej Kaczyński

Abstract

We present the analysis of the stress-and-strain state of a contact couple formed by two isotropic semi-infinite solids one of which has a small surface groove. Based on the classical fracture criteria, namely, on the criterion of maximal principal stresses and the criterion of maximal shear stresses, we determine the regions of the most possible formation of the zones of crack initiation and plastic zones. Brittle cracking can be induced both by tensile and compressive stresses arising on the interface. For some shapes of the groove considered as an example, our analysis reveals that the fracture process starts from the boundary of contacting solids.
