“…It is extremely important for strength design to consider these steep stress distributions because the failure of ceramics is caused only by insensible growth of a pre-defect. As part of the study of the chipping damage and compression failure, authors reported on the contact problems of a sphere/sphere [5] and a plate/sphere [6,7] of brittle materials. These papers are reported the usefulness for the strength design evaluating from a viewpoint of fracture mechanics.…”

Stress distributions beneath the contact surface of ceramic plat in contact with round bar were analyzed by 3-D FEM. On the basis of analytical results, the contact strength was evaluated by considering varied sizes and positions of pre-existing defects from a viewpoint of fracture mechanics. The contact rupture occurs from a surface defect that pre-exists in the vicinity of the edge of the plate. If we posit the premise that a defect size and a distance from contact boundary to its defect, the contact rapture load can be evaluated by using the proposed equation.
