摘要

目的旨在明确SLM制备的316L不锈钢的力学性能,建立适用于该材料的动态本构关系。方法采用SLM制备的316L不锈钢进行拉伸试样与压缩试样,对哑铃形拉伸试样开展了准静态拉伸实验,并对圆柱形压缩试样实施了动态压缩实验,系统评估了其在多种应变率下的力学性能。结果基于实验数据,计算得出在准静态和动态加载下的应力-应变曲线,显示出明显的应变率强化效应并拟合得到了适用于该材料的Johnson-Cook本构模型,该模型能够较好地描述SLM成形316L不锈钢的静/动态力学行为。结论本研究发现SLM工艺能提升316L不锈钢的力学性能,并且成功建立了适用于该材料的动态本构关系。本研究可为SLM制备316L不锈钢在防护工程应用提供实验依据与理论参考。

Abstract

The work aims to clarify the mechanical properties of 316L stainless steel prepared by selective laser melting (SLM) and establish a dynamic constitutive relation suitable for this material. SLM-fabricated 316L stainless steel was used for tensile and compression samples. Quasi-static tensile tests were conducted on dumbbell-shaped samples, while dynamic compression tests were performed on cylindrical specimens to systematically evaluate their mechanical properties under various strain rates. Based on experimental data, stress-strain curves under quasi-static and dynamic loading were calculated. A Johnson-Cook constitutive model suitable for this material was fitted, which effectively described the static/dynamic mechanical behavior of SLM-fabricated 316L stainless steel. This study finds that the SLM process can enhance the mechanical properties of 316L stainless steel and successfully establishes a dynamic constitutive relationship suitable for this material. This study provides experimental evidence and theoretical reference for the application of SLM-fabricated 316L stainless steel in protective engineering.
