A new approach to porous materials modelling is presented, in which random void cells are considered within an iron matrix. The system is solved by means of a recent numerical method, the Cell Method. The Young modulus of four sintered alloys is computed and the simulation shows a good agreement with experimental results reported in literature, depending on the porosity of the sintered powder and the Young modulus of the wrought material. Besides this application, the approach is promising in a wider class of problems, namely all those in which a large number of random distributed heterogeneities is present.

Abstract
A new approach to porous materials modelling is presented, in which random void cells are considered within an iron matrix. The system is solved by means of a recent numerical method, the Cell Method. The Young modulus of four sintered alloys is computed and the simulation shows a good agreement with experimental results reported in literature, depending on the porosity of the sintered powder and the Young modulus of the wrought material. Besides this application, the approach is promising in a wider class of problems, namely all those in which a large number of random distributed heterogeneities is present.File in questo prodotto:
