轴向撞击杆中动应力集中系数的测定

THE MEASUREMENT OF DYNAMIC STRESS CONCENTRATION FACTORS IN THE AXIAL IMPACT BAR

本文用MLIS超小型半导体应变计测量轴向撞击杆中的动应力集中系数,实验结果和数值计算符合较好。

The dynamic stress concentration factors in the axial impact bar are measured with the MLIS superminiaiture semi-conductor strain gauge, the experimental results are compared with the numerical calculation and have good agreement.
