dc.description.abstractNatural porous materials have a large area of usage, from micromechanical designs to medical applications, due to their geometrical forms and chemical properties. Mechanical properties of porous materials are usually performed after several homogenized applications because of their complex geometric forms. It is known that usage of homogenized details of microarchitecture in macro structural analyses provides savings in terms time and computational effort. However, realistic analyses are performed by including microarchitectural details in models, due to advancing technology and reverse engineering techniques.In this study, modal properties of a porous structure are investigated by taking microstructural details into consideration according to the voxel-based finite element model, and significant modal behavior properties, which cannot be observed in routine modal analyses, are determined. In addition, analyses using the homogenized model of porous structure are performed, and it is seen that the obtained results are not only different numerically but also have different modal behavior from the porous model. Special modes, defined as local modes, which are not seen in homogenized models, are observed in models by using the voxel-based finite element method and analyses are comprehensively performed. © The Author(s) 2013.
