MODELING OF INTERFACE STRENGTH AS WELL AS INTERFACE DEFORMATION BASED ON NANOMECHANICS AND DEVELOPMENT OF INTERFACE DATABASE SYSTEMS
… focus on the shear deformation that occurs in interfaces of such materials when overall three-dimensional hierarchy is subjected to mechanical loading. In order to predict the interface stress magnitude in such systems during deformation, steered molecular dynamics simulations are performed to …

Design of Improved Ceramic/polymeric Composites
… for glass fiber/epoxy matrix composites. This interface consisted of a thin coating of activated carbon (ACI) with high surface area to take advantage of mechanical interlocking. Furthermore, the surface chemistry was modified to provide varying degrees of bonding to the resin. These ACI …

Enhancement of Shaft Capacity of Cast-in-Place Piles Using a Hook System
… the effect of passive inclusion on pile-soil interface shear strength behaviour, employing a modified direct shear test apparatus. The interface strength obtained for pile-soil specimens was found to significantly increase when passive inclusions were implemented. Residual friction angle for …

Fatigue damage mechanisms in fiber reinforced composite materials including the effect of cyclic loading frequency
… for the effects of frequency and fiber/matrix interface strength, is developed. Using a first law analysis, a good correlation between acoustic and thermal emission with damage propagation and extent is developed. Finally, a new conceptual theory, called the Strain Energy Release-Potential …

Interfacial adhesion of thin film high energy density anode materials
… cycling, little work has been done to study the interface strength of Ni/a-Si systems. Here, we investigate Ni/a-Si interfacial adhesion strength through the technique of laser spallation (LS) combined with finite element analysis (FEA). It was found that the Ni/a-Si interface can withstand at …

Indentation testing of composite materials: a novel approach to measuring interfacial characteristics and engineering properties
… as an attempt to evaluate the interfacial shear strength at a mesolevel, possibly overcoming the deficiencies of present techniques. Vickers Microhardness Testing and Continuous Ball Indentation Testing (CBIT) of composite materials provided data for assessing the sensitivity of indentation …

Computational Modeling and Simulation of Viscoelastic Granular Packings
… efficiently. A specific focus is given to interface strength in deformable granular systems, particularly in the context of vitrimers compaction. An analytical model is developed to investigate the evolution of chain density at the interface between different networks, resulting in a …

Emergence of Delamination Fractures around Casing and Its Stability
… The complex failure behavior of cement/rock interfaces observed in the laboratory experiments does not look like the behavior of linear or simple nonlinear mechanical interfaces. Cohesive zone method (CZM) with BK-form bilinear traction separation law can be a good candidate to reproduce the …

Analyzing the effects of product architecture on technical communication in product development organizations
… the product architecture by documenting design interfaces, 2) capture the development organization by documenting team interactions, and 3) couple the product architecture with the development organization by comparing design interfaces with team interactions. Our approach is illustrated by …

Histological and Mechanical Analysis of Bone/Implant Interface in Female Retired-Breeder Rabbits
… and histological aspects of the bone/metal interface of endosseous titanium implants in compact and trabecular bone. Two implants were placed: one in the distal metaphysis (M) and one 2.0 cm proximal in the diaphysis (D). Right side limbs were subjected to a sham surgery and served as …

Micromechanics of Granular Media: A Fundamental Study of Interphase Systems
… geometry controls the degree of granular media strength mobilization by controlling development of fabric and contact force anisotropy inside the interphase region. A unique bilinear relationship exists between the mobilized granular media strength and the principal direction of average contact …

Modelling the mechanical behaviour of the interface between prosthesis and bone
The integrity of the cement-bone interface is vital to the long term stability of cemented arthroplasty. Although the factors affecting the strength of the cement-bone interface are well documented the behaviour and load transfer across the interface at the trabecular level has been largely …

Study of intermetallic compound layer formation, growth and evaluation of shear strength of lead-free solder joints
… solder joint reliability include the bonding strength, the voiding percentage in joints, the size of the voids and their location within the joint. The work reported in this thesis on formation and growth of intermetallic compound layer, and evaluation of the shear strength of lead-free solder …
