Perfect crystals grown from imperfect interfaces [PDF]

open access: yesScientific Reports, 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.

Stress-strain fields and the effectiveness shear properties for three-phase composites with imperfect interface

open access: yes, 2000
Based on the 'average stress in the matrix' concept of Mori and Tanaka (:Mori, T., Tanaka, K., 1973. Average stress in matrix and average elastic energy of materials with misfitting inclusion. Acta Metall.

Numerical implementation of imperfect interfaces [PDF]

open access: yesComputational 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.

A Study of Failure Strength for Fiber-Reinforced Composite Laminates with Consideration of Interface

open access: yesAdvances in Materials Science and Engineering, 2015
Composite laminates can exhibit the nonlinear properties due to the fiber/matrix interface debonding and matrix plastic deformation. In this paper, by incorporating the interface stress-displacement relations between fibers and matrix, as well as the ...

Derivation of imperfect interface models coupling damage and temperature [PDF]

open access: yes, 2019
In this paper we introduce a model describing a layered structure composed by two thermoelastic adherents and a thin adhesive subject to a degradation process.

Effect of initial stress on the reflection and transmission of shear horizontal waves at the interface between two transversely isotropic elastic half-spaces

open access: yesVietnam Journal of Mechanics
The phenomenon of reflection and transmission of shear wave (horizontally polarized) at an imperfect interface between two different transversely isotropic elastic half-spaces is investigated in this paper.

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system

open access: yesFEBS Letters, EarlyView.
Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.
