SIMULATION STUDY OF STRESS-STRAIN CURVE OF STAINLESS STEEL SUS304

Abstract

SUS304 is a type of stainless steel (also known as inox) which is a very popular and widely used material in the world today. SUS304 has many outstanding advantages such as good corrosion resistance, high durability, easy processing, high aesthetics and safety for health. Therefore, this material is used in most applications in all fields such as food, medicine, architectural works, etc. In this study, the stress-strain curve of SUS304 stainless steel was simulated. From there, it shows how SUS304 stainless steel reacts under load and provides important information about its tensile strength, hardness, plastic deformation ability and resistance to destruction. The simulation results indicate that (1) The initial slope of the stress-strain curve indicates the stiffness of the material, i.e., the ability to resist initial deformation under load; (2) The point on the stress-strain curve where the material begins to deform permanently is the yield strength; (3) The highest point on the stress-strain curve indicates the maximum tensile strength of the material before it begins to contract and eventually fracture; (4) The distance from the yield point to the fracture point indicates the plastic deformation ability of the SUS304 material, and (5) The stress-strain curve ends at the fracture point, indicating the ultimate load-bearing capacity of the material.
