Friction and wear of brittle materials during sliding contact are often associated with the fracture-induced failure of interlocking asperities under shear loading. This paper presents analytical, numerical and experimental studies of an idealized asperity under lateral load. The material under study was chosen as PMMA. Both experimental and numerical studies were done for different asperity base angle (θ), from 60 to 90 degrees. Maximum force to initiate the crack and also crack initiation angle were derived from analytical, numerical, and experimental investigations. The results showed that the maximum force went higher for smaller θ angle, along with good agreements between all the three approaches.
