Interface imperfections in metal/Si multilayers
Journal of Applied Physics, 1992The structural and optical properties of Mo/Si and Ru/Si x-ray multilayers prepared by sputter deposition in argon have been examined using high-resolution transmission electron microscopy, optical profilometry, and x-ray and soft x-ray reflectance. We find that for Ru/Si, similar to previous results for Mo/Si, lower argon pressure during deposition ...

Imperfect Interfaces and Discrete Lattice Structures
Journal of Engineering Materials and Technology, 2002We propose a model where a lattice structure is used within an interface layer of finite thickness. An evolution problem is set and studied to analyze the structural changes within the interface during the deformation. Numerical examples are presented for the case of a triangular lattice structure.

Thin interphase/imperfect interface in conduction
Journal of Applied Physics, 2001Thin interphase between two media is modeled in terms of imperfect interface conditions in the context of potential theory, thus for conduction, dielectric behavior, and permeability. There is no limitation on the magnitude of interphase material conductivity.

An analysis of decohesion along an imperfect interface
International Journal of Fracture, 1990A cohesive zone type interface model, taking full account of finite geometry changes, is used to study the decohesion of a viscoplastic block from a rigid substrate. The specific boundary value problem analyzed is a plane strain one with the imposed loading corresponding to overall uniaxial straining.

Cracked Laminates with Imperfect Interlaminar Interface
1995Variational analysis of cracked laminates with imperfect inter-laminar interface is developed on the basis of a generalized extemum principle of thermoelastic complementary energy. Closed form results for effective Young’s modulus, thermal expansion coefficient, shear modulus and internal stresses are developed for cracked cross-ply laminates.

Computational Homogenization Accounting for Imperfect Interfaces
2023Composite materials have been firmly integrated into modern life due to their superior physical and functional qualities. These multifunctional materials have proven as promising alternatives to conventional materials in various applications. Predicting the behavior of composites is a severe challenge mainly because their responses originate from their
