High-frequency homogenization in periodic media with imperfect interfaces [PDF]
Proceedings of the Royal Society A: Mathematical, Physical and Engineering Sciences, 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 periodic cell.

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.

Numerical implementation of imperfect interfaces [PDF]
Computational Materials Science, 2007 One approach to characterizing interfacial stiffness is to introduce imperfect interfaces that allow displacement discontinuities whose magnitudes depend on interfacial traction and on properties of the interface or interphase region. This work implemented such imperfect interfaces into both finite element analysis and the material point method.

Magnetoelectric effects in multiferroic laminated plates with imperfect interfaces
Theoretical and Applied Mechanics Letters, 2017 Two-dimensional (2D) equations for multiferroic (MF) laminated plates with imperfect interfaces are established in this paper. The interface between two adjacent sublayers, which are not perfectly bonded together, is modeled as a general spring-type ...

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 ...

Influence of boundary conditions on the response of multilayered plates with cohesive interfaces and delaminations using a homogenized approach [PDF]
Fracture and Structural Integrity, 2014 Stress and displacement fields in multilayered composites with interfacial imperfections, such as imperfect bonding of the layers or delaminations, or where the plies are separated by thin interlayers allowing relative motion, have large variations in ...
