Sažetak
The paper presents a method for modeling the geometrical features of real metal open-cell foams by means of computer tomography and 3D image analysis. A sample of open-cell metal foam was scanned using a computer tomography and the resulting data was used to create a 3D foam model from voxels. Image processing technique called "volume thinning" was used to extract the foam skeleton model, which was used for construction of finite element model using lattice modeling technique. The validation of the model was carried out using a compression simulation in comparison with experimental testing. The results show a very good agreement between the stress-strain curves obtained using simulations and experiments and so justify the use of lattice modeling for further research of open-cell foam behavior.
