摘要: Abstract This paper addresses the issue of effective diffusion properties materials with complex microstructure. By using micromechanical tools, we present a finite element based model suitable for arbitrary shaped and composite inclusion problem in framework properties. A new reformulation Eshelby ( Eshelby, 1957 ) aiming at saving calculation time is presented, solved results compared to that classical approach consisting imposing Hashin-type boundary condition external mesh. Furthermore, established used compute second order concentration tensors resulting from resolution different configurations. The impact parameters such as distributions phases (in inclusion) on are also studied discussed. Finally, concept equivalent investigated work proposed an alternative way handle inclusions under some specific conditions. thermal or electrical conduction problems since these correspond mathematically elliptic ones.
