Modeling Interface Damage with Random Interface Strength on Asphalt Concrete Impervious Facings. [PDF]
Asphalt concrete impervious facings, widely adopted as the impervious structures for rockfill dams and upper reservoirs in pumped storage power stations, typically have a multilayer structure with a thin sealing layer, a thick impervious layer, and a thick leveling bonding layer. The properties of the interfaces between these layers are crucial for the

Shear-Mode Viscoelastic Damage Formulation Interface Element [PDF]
In this paper, a viscoelastic-damage cohesive zone model is formulated and discussed. The interface element constitutive law has two elastic and damage regimes. Viscoelastic behaviour has been assumed for the shear stress in the elastic regime. Three element Voigt model has been used for the formulation of relaxation modulus of the material.

A Multi-Level Interface Model for Damaged Masonry [PDF]
The aim of the present work is to propose a new micro-mechanical model in the context of the deductive approach used to derive interface models. This model, based on a previous study introduced previously by A. Rekik and F. Lebon, is used to reproduce the damage in masonry by combining structural analysis and homogenization methods.

Damage at heterogeneous interfaces [PDF]
We discuss the progressive damage of an heterogeneous interface modelled through a fiber bundle with random strength, coupled to two semi-infinite elastic blocks. We show that a hierarchical description of the elastic blocks and an homogeneous damageable interface gives rise to a cascade of bifurcations associated to the progressive concentration of ...

Homogenization Methods for Interface Modelling in Damaged Masonry [PDF]
The aim of the present study was to reproduce damage in masonry by combining structural analysis and homogenization methods. In the case of a masonry structure composed of bricks and mortar, a third material is assumed to exist, which is a mixture of the two materials sandwiched between the other two.

A model of imperfect interface with damage [PDF]
In this paper two models of damaged materials are presented. The first one describes a structure composed by two adherents and an adhesive which is micro-cracked and subject to two different regimes, one in traction and one in compression. The second model is a model of interface derived from the first one through an asymptotic analysis, and it can be ...

Measurement of Interface Damage Heterogeneity [PDF]
Both stereological and direct experimental procedures of estimating the distribution of interface normal orientations in a polycrystalline material are discussed in connection with the problem of intergranular damage heterogeneity. Two stereological procedures of obtaining the interface normal orientation distribution are compared.

A thermodynamically consistent derivation of a frictional-damage cohesive-zone model with different mode i and mode II fracture energies [PDF]
The present paper deals with the derivation of an interface model characterized by macroscopic fracture energies which are different in modes I and II, the macroscopic fracture energy being the total energy dissipated per unit of fracture area.
