Abstract
AbstractThis work determines analytically normalized mode I and mode II stress intensity factor (SIF) of a Brazilian disc having a central inclined crack with smooth surfaces. Two basic types of loading are considered: (1) partial compression with uniform pressure and (2) two‐force diametric compression with confining pressure. The present analysis is based on a widely used published solution of the SIFs of the cracked disc as a result of applying two‐force diametric compression. Wide‐range parameters controlling the behavior of the disc are considered. The parameters involve relative crack length, crack inclination, half‐pressure angle, and confining pressure. The conditions required for transmitting from mixed‐mode I/II loading to pure mode II loading are well defined. Good agreement has been generally obtained with relevant results found in the literature.
