Residual Stress and Deformation Energy Under Ground Surfaces of Brittle Solids

This work deals with the determination and description of the deformation energy, which is accumulated under the surface of brittle solids, especially those of optical glass, during the free abrasive grinding process. The distribution of deformation energy density in depth under the ground surface was investigated in this work. We arrived at a new model for the free abrasive grinding process by making use of the deformation energy density which was experimentally determined in relation to the abrasive size, grinding rate and supplied input power. Further, the validity of our model was tested against a series of relations between process parameters which were derived by other authors.
