Multi-scale modeling of imperfect interfaces and applications [PDF]
, 2015 International audienceThis lecture is devoted to the modeling of imperfect interfaces, i.e. models takes into account a jump in thedisplacements field and/or a jump in the stress vector due to the interface. In this paper, a family of interface models is

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.

High-frequency homogenization in periodic media with imperfect interfaces. [PDF]
Proc Math Phys Eng Sci, 2020 In this work, the concept of high-frequency homogenization is extended to the case of one-dimensional periodic media with imperfect interfaces of the spring-mass type. In other words, when considering the propagation of elastic waves in such media, displacement and stress discontinuities are allowed across the borders of the ...

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 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.
