为秦山核电站反应堆压力容器辐照监督管提供了两种可供使用的J_(1,c)拉伸试验样品的几何尺寸:(1)“W”型14×10×45mm;(2)半圆型φ43×15mm,并给出它们的J积分表达式:(1)“W”型 J=2U/B(W-a)-0.388 U_e/(W-a)
Two kinds of J_ (1, c) tensile test samples are available for the reactor pressure vessel irradiation supervisory tube of Qinshan Nuclear Power Station: (1) “W” type 14 × 10 × 45mm; (2) Semicircular φ43 × 15mm, and give their J integral expression: (1) “W” type J = 2U / B (Wa) -0.388 U_e / (Wa)
