Abstract

ABSTRACT Molecular dynamics simulation simulates the deformation of Fe Cr alloy containing notches under tensile loading. The objective is to explore the relationship between the influence of the failure behavior of Fe Cr alloy and notches. The findings show that the average grain size is the critical value. When the notch size is larger than the critical value, the shear stress is concentrated with the root of the sample notch, conversely, when the notch size is less than or equal to the average grain size, the shear strain is uniformly distributed in the sample. The notch sensitivity of Fe Cr alloy is independent of average grain size by constructing different models for comparison.
