Indentation of sintered alumina clay composite - an experimental discussion of a combined Boussinesq and blister stress field approach

By Ananya Mukhopadhy and SK Biswas


Surface elastic strain field generated in conical indentation of sintered alumina clay composite was measured to verify the suitability of a superposed combination of Boussinesq and blister stress fields, used previously for analysing the indentation problem. The residual strain measured in the elastic hinterland is used to estimate the blister field strength without any reference to stress relation within that field. The approach may be useful in fracture studies of brittle materials
