Indirect Determination of Material Properties of Closed-Cell Metal Foam: Comparison of Voxel and Tetrahedral Finite Element Models
Original language description
In this paper a comprehensive evaluation of the microstructural finite element (micro- FE) models of closed-cell aluminum metal foam is given. Comparison of models developed using high resolution three-dimensional image data obtained using microtomographic scanning of a sample with different resolutions is presented. Two sets of micro-finite element models are prepared using the same image data: i) voxel finite element models ii) tetrahedral finite element models. A virtual uni-axial compression test issimulated in threemutually perpendicular directions to obtain the elastic moduli and the maximum values of the principal stresses as well as to quantify the anisotropy of the back-calculated material characteristics. The requirements in terms of the minimal spatial resolution of the microtomographic images needed for proper estimation of elastic properties of a closed-cell metal foams are given.
