摘要：

It has been made clear that the values of the fracture toughness of structural ceramics can be accurately obtained by applying the highly skilled technique of cutting a THE-shaped notch sharply into the single edge notched beam (SENB) and chevron notch (CN) methods. These improved methods are referred to as the SEVNB and CVN methods, respectively, which are made possible by using a THE-shaped slicing diamond wheel in cutting. Several kinds of ceramics were evaluated by these methods and the values were compared with those obtained by the single edge precracked beam (SEPB) and conventional CN methods. The values of the fracture toughness scattered only slightly and agreed quite well with one another, except for in the conventional CN method.
