An approach for the modeling of interface-body coupled nonlocal damage [PDF]
Fracture and Structural Integrity, 2013 Fiber Reinforced Plastic (FRP) can be used for strengthening concrete or masonry constructions. One of the main problem in the use of FRP is the possible detachment of the reinforcement from the support material. This paper deals with the modeling of the

A Multi-Level Interface Model for Damaged Masonry [PDF]
Civil-Comp Proceedings, 2013 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.

Shear-Mode Viscoelastic Damage Formulation Interface Element [PDF]
Key Engineering Materials, 2016 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.

Interface damage model for fatigue-driven fracture [PDF]
MATEC Web of Conferences, 2018 A fatigue interface damage model is presented that is based on combining a fatigue evolution law with a static interface damage model. The fatigue model elegantly enables the simulation of crack initiation and propagation in a computationally efficient ...

Modeling Interface Damage with Random Interface Strength on Asphalt Concrete Impervious Facings. [PDF]
Materials (Basel)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

Damage Strength Model of Soil–Structure Interface Based on Equivalent Damage
工程科学与技术Objective Pile-soil interaction plays a critical role in slope support engineering. Since the contact surface represents the weakest link in the system, analyzing the influence of the soil shear area on the mechanical properties and the constitutive ...

Damage at heterogeneous interfaces [PDF]
Physica A: Statistical Mechanics and its Applications, 1999 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 ...

Fatigue Damage Analysis of Composite Insulator Cor Rod/sheath Interface [PDF]
MATEC Web of Conferences, 2019 A self-made fatigue testing machine was used to simulate the damage process of the insulator interface under working conditions and the damage degree is evaluated by the compressive shear test. The improved interface adhesion model reflects the interface

Initial damage analysis in bone cement-stem debonding procession of cemented hip arthropsty
Materials & Design, 2023 The initial interface debonding damage behavior of cemented hip arthroplasty was simulated and investigated through the push-in experiment. A series of nondestructive testing techniques were carried out to detect damage to the stem-cement interface and ...
