本文总结了用国际焊接学会所推荐的深、浅缺口插销形状进行的对比试验。尽管采用的缺口深度不一样,但其临界应力值σ_(crimp)仍较高。试验再次证明这种低碳钢塑性好,无延迟裂纹破坏的特征。本试验采用“断裂”准则。
This article summarizes the comparative tests carried out with the shape of the deep and shallow notch pins recommended by the International Welding Society. Although the notch depth is not the same, its critical stress value σ crimp is still high. Test again proved that this low-carbon steel plastic, no delay crack damage characteristics. This test uses the “fracture” guidelines.
