| dc.description.abstract1 | In this work, a multiscale homogenization procedure using the boundary element method
(BEM) for modeling a two-dimensional (2D) and three-dimensional (3D) multiphase microstructure is
presented. A numerical routine is specially written for modeling nodular cast iron (NCI) considering
the graphite nodules as cylindrical and real geometries. The BEM is used as a numerical approach
for solving the elastic problem of a representative volume element from a mean field model.
Numerical models for NCI have generally been developed considering the graphite nodules as voids
due to their soft feature. In this sense, three numerical models are developed, and the homogenization
procedure is carried out considering the graphite nodules as non-voids. Experimental tensile,
hardness, and microhardness tests are performed to determine the mechanical properties of the overall
material, matrix, and inclusion nodules, respectively. The nodule sizes, distributions, and chemical
compositions are determined by laser scanning microscopy, an X-ray computerized microtomography
system (micro-CT), and energy-dispersive X-ray (EDX) spectroscopy, respectively. For the numerical
model with real inclusions, the boundary mesh is obtained from micro-CT data. The effective
properties obtained by considering the real and synthetic nodules’ geometries are compared with
those obtained from the experimental work and the existing literature. The final results considering
both approaches demonstrate a good agreement. | pt_BR |
