摘　　要：采用ANSYS有限元分析软件,建立含不同种类、形态夹杂物的硅锰钢有限元模型,计算在单向拉伸状态下含夹杂物的硅锰钢应力场分布,进而从宏观力学角度分析夹杂物的力学行为。结果表明,夹杂物和基体的弹性模量的差距及夹杂物的形态,对试样内的应力集中程度及最大应力影响最显著。The mechanical properties of the steel is controlled by types, morphology, amounts, size and distribution of inclusions in the Si-Mn steel. Finite element model of Si-Mn alloy with various types and morphologies inclusions have been established to simulate the stress distribution in Si-Mn alloy with inclusions in the condition of tension and to analyze the mechanical behavior of inclusion in macro-mechanical properties based on ANSYS software. It was revealed that the stress concentration and maximum stress in the Si-Mn alloy samples are mainly affected by the gradient of elastic modulus between inclusions and the matrix and the morphologies of the inclusions
