The Stefan Problem With an Imperfect Thermal Contact at the Interface

Journal of Applied Mechanics, 1982
The Stefan problem in a semi-infinite region with arbitrarily prescribed initial and boundary conditions, subject to a condition of the mixed type at the interface is investigated. To establish the exact solution of the problem, some new basic solutions of the heat equation are offered. Their mathematical properties are also supplied.

Interface imperfections in metal/Si multilayers

Journal of Applied Physics, 1992
The 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, 2002
We 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.

Homogenization of a composite with imperfect interface

2004
In this paper the homogenization of the stationary heat equation with rapidly oscillating coefficients in a two-component composite with imperfect inclusions is studied. According to the values of a parameter γ, describing the thermal resistance of the interface separating the two materials, different limit behaviours are obtained.

Thin interphase/imperfect interface in conduction

Journal of Applied Physics, 2001
Thin 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, 1990
A 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

1995
Variational 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.
