Taylor杆常被用于确定材料动力学行为和损伤特性的常用实验。文章开展了低碳钢的霍普金森压杆实验和缺口拉伸实验，并基于J-C模型和B-W损伤模型确定了船用低碳钢的动力学特性。开展了150-250 m/s速度内的Taylor杆撞击实验的仿真，划分了应力波不同效应的4个阶段，确定了大塑形变形、延性损伤和剪切损伤等3种典型损伤模式。该文为确定船用钢在爆炸冲击载荷下的损伤特性提供了参考。

Taylor impact tests are used as experimental and numerical tests for determining the me-chanical behavior and damage performance of ship steels subjected to high strain rates. SHPB, Notched tension tests were taken to investigate the constitutive relation and fracture characteristics with B-W damage criterion. Taylor impact tests are numerically simulated in velocity range from 150 m/s to 250 m/s. There are four stages in the process of Taylor bar impacting the target. Three failure modes generate:large plastic deformation, ductile damage and shear damage, which stress tri-axiality have an obvious effect on.
