Generalization of the micromechanics multi-coating approach to coupled fields composite materials with eigenfields: Effective properties

摘要: Abstract A generalization of the micromechanics multi-coating scheme to coupled fields composite materials with eigenfields is presented in this work. The key ingredients required succeed are: (i) use pseudo-tensors represent properties material phases and proper handling induced pseudo-tensorial relations, (ii) introduction eigenfields, (iii) derivation interfacial operators for account jump gradient potential fields. model used compute thermo-magneto-electro-elastic effective piezomagnetic results agree well numerical predictions reported literature. This general framework may be useful containing functionally graded inhomogeneities or inhomogeneous interphases. optimal design such smart will discussed elsewhere.
