3D XFEM Modelling of Imperfect Interfaces
, 2013 In this paper, recent contributions to the modelling of coated inclusions by means of an eXtended Finite Element Method are presented. The matrix particle interface is modelled as a finite thickness, imperfect interface. Two approaches are considered: a variational approach inspired to Suquet’s work on asymptotic analysis of thin layers, and an ...

Multiscale Modeling of Imperfect Interfaces and Applications [PDF]
, 2016 Modeling interfaces between solids is of great importance in the fields of mechanical and civil engineering. Solid/solid interface behavior at the microscale has a strong influence on the strength of structures at the macroscale, such as gluing, optical systems, aircraft tires, pavement layers and masonry, for instance.

Thermo-mechanical Loading of Laminates with Imperfect Interfaces [PDF]
Procedia Engineering, 2014 AbstractComposite laminates are currently being pursued for structures which may be subjected to explosive threats in aggressive environments, characterized by extreme temperatures and seawater. A mechanical model is formulated for laminated plates subjected to thermo-mechanical loading and deforming in cylindrical bending; the layers are assumed to be

Perfect crystals grown from imperfect interfaces. [PDF]
Sci Rep, 2013 The fabrication of advanced devices increasingly requires materials with different properties to be combined in the form of monolithic heterostructures. In practice this means growing epitaxial semiconductor layers on substrates often greatly differing in lattice parameters and thermal expansion coefficients.

Composites with imperfect interface [PDF]
Proceedings of the Royal Society of London. Series A: Mathematical, Physical and Engineering Sciences, 1996 The authors present a new variational principle and bounds to describe the effective conductivity tensor for anisotropic two-phase heat conducting composites with interfacial surface resistance between phases. New upper bounds are given in terms of the two-correlation functions, component volume fractions, and the moment of inertia tensor for the ...

On Saint Venant - Kirchhoff imperfect interfaces [PDF]
International Journal of Non-Linear Mechanics, 2017 Using matched asymptotic expansions with fractional exponents, we obtain original transmission conditions describing the limit behavior for soft, hard and rigid thin interphases obeying the Saint Venant-Kirchhoff material model. The novel transmission conditions, generalizing the classical linear imperfect interface model, are discussed and compared ...

On Oscillation of Inhomogeneous Fibres with Imperfect Interfaces [PDF]
The Quarterly Journal of Mechanics and Applied Mathematics, 2001 Summary: This work deals with an asymptotic model of oscillation of an inhomogeneous fibre containing a layer of imperfect interface (thin adhesive layer). We derive a lower-dimensional model and study propagation of waves associated with the displacement jump across the interface.
