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.
