Finite Element Analysis on Ground Residual Stresses of Ceramic

摘要

Ceramic residual stress originates mostly from the plastic deformation on the surface and sub-surface under the action of grinding force and grinding temperature. In this paper, the magnitude and distributing laws of residual stresses were researched via finite element method (FEM) and were testified through X-ray diffraction experiment method. The residual stress on grinding ceramic surface is tensile stress and compressive stress occurs in certain depth sub-surface and the stress becomes zero in deeper layer. The magnitude, acting depth and variation of residual stress are mostly influenced by the normal grinding force.
