发布时间：2018-08-07 15:44
【摘要】：利用传统力学试验方式直接获取实际工程结构的(如焊接接头)材料力学性能有时相当困难,而准确的材料力学参数是分析实际工程结构完整性的重要基础依据。鉴于获取材料表面维氏硬度相对容易,文中利用维氏硬度试验和ABAQUS有限元分析相结合的方式,分析了304奥氏体不锈钢维氏硬度与材料屈服应力的相关性,为复杂工程结构的材料力学参数确定提供了一条新的途径。
[Abstract]:It is very difficult to obtain the mechanical properties of practical engineering structures (such as welded joints) directly by using the traditional mechanical test method, and the accurate mechanical parameters of materials are the important basis for analyzing the integrity of practical engineering structures. Since the Vickers hardness on the surface of the material is relatively easy to obtain, the correlation between the Vickers hardness of 304 austenitic stainless steel and the yield stress of the material is analyzed by using Vickers hardness test and ABAQUS finite element analysis. It provides a new way for the determination of material mechanics parameters of complex engineering structures.
