抜粋

In this study, in order to calculate dangerous volume at various stress distribution, the dangerous volume quantification method is proposed. And in order to predict stress distribution of spray coating, an easy calculation method of residual stress distribution based on the first report is proposed. The calculated dangerous volume in alumina's spray coating on titanium layer is different from alumina's spray oating single layer. The difference is based on stress distribution in alumina's spray coating. The fracture strengths predicted with the proposed method and the third report are appropriate to experimental results obtained by 4-point bending tests. Therefore dangerous volume calculation in thermal stress distribution that is different from mechanical stress distribution also become possible.
