ABSTRAKT

A new and efficient approach to generate dedicated three-dimensional (3D) finite element meshes for further multiscale analysis of polycrystalline microstructure behavior under loading conditions is the subject of the present research. An explicit image of microstructure is created on the basis of a digital material representation approach. The Monte Carlo (MC) method is used in order to obtain 3D representation of the investigated morphology. Then, information obtained from the MC method is transferred to the initial, coarse, finite element mesh. This mesh in the subsequent steps of the developed approach is modified based on the information provided from the adaptive finite element solver. The two phase ferriticmartensitic microstructure is selected as a case study. A description of the proposed finite element mesh generation algorithm as well as an example of application of the obtained mesh to the multiscale model of plastic deformation under tension are presented in the paper.
