摘要

作为Q345钢的替代钢种，Q355钢将于2019年2月起大量应用于建筑工程中。基于结构抗冲击爆炸性能研究的需要，其动态材料性能的研究具有迫切性和必要性。应用万能材料试验机与分离式霍普金森压杆系统对Q355B钢在不同温度、应变率及应力状态下的力学性能进行了研究。发现塑性流动应力与断裂应变随温度的上升分别呈现非线性下降与上升趋势，采用试验为主数值模拟为辅的方法分别标定了修正Johnson-Cook本构关系与修正Johnson-Cook断裂准则。最后，开展了Q355B钢Taylor撞击试验，验证了修正Johnson-Cook模型及其参数标定的有效性。

Abstract

As a substitute of Q345 steel, Q355 steel will be largely applied in construction engineering. Due to the demand of structural engineering for shock and explosion, the research on the dynamic material behavior of it is urgent and necessary. Research on the mechanical properties of Q355B steel at different temperatures, stain rate and stain condition were investigated using universal testing machine and split Hopkinson pressure bar system. It was found that plastic flow stress nonlinearly was decreased and fracture stain nonlinearly was increased with the increase of temperature. Then, modified Johnson-Cook constitutive relation and fracture criteria were calibrated respectively by using test results and numerical simulations. Finally, Taylor impact test was carried out to verify the validity of MJC model and its parameter values.
