On Oscillation of Layered Structures with Imperfect Interfaces
2006Asymptotic models are considered for propagation of waves in layered structures containing imperfect interfaces. An imperfect interface is defined as a surface where unknown functions and their derivatives may have discontinuities. For thin layered structures we derive lower dimensional models and analyze the dispersion equations for propagating waves.

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.

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.

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
