根据辐照监督管的特定形状,设计了半圆形非标准拉伸试样。用多试样柔度法测出的常温JIC值与按标准试验测得的值吻合得很好。 According to the specific shape of the radiation supervision tube, a semi-circular non-standard tensile specimen was designed. The JIC value measured at room temperature by the multi-sample compliance method is in good agreement with the value measured by the standard test.
