Abstract

Micromechanics is the analysis of composite or heterogeneous materials on the level of the individual phases that constitute these materials. In this project micromechanical structure of ferritic/pearlitic steels was modeled by two methods. First SHA model (stacked hexagonal array) and second the real microstructure of the steels. FE analysis was performed to investigate the influence of some parameters such as volume fraction and aspect ratio of the second phase on deformation behavior and also macroscopic and microscopic responses to tension and shear. The stressstrain curves from FE analysis of both models and experimental results obtained from some papers were similar. Afterward, a comparison between averages strains in different types of steel were performed that shows a rise by increasing pearlite volume fraction in steels.
