Using the simple peel test to measure the adhesive fracture energy, Ga [PDF]

open access: yes, 2012
The adhesive fracture energy of structural adhesive joints may be readily ascertained from linear-elastic fracture-mechanics (LEFM) methods, and indeed an ISO Test Method (ISO 25217: 2009) now exists for the LEFM Mode I value, Gc, as a result of the ...

Atomistic Simulations of Nanotube Fracture

open access: yes, 2002
The fracture of carbon nanotubes is studied by atomistic simulations. The fracture behavior is found to be almost independent of the separation energy and to depend primarily on the inflection point in the interatomic potential.

High-accuracy phase-field models for brittle fracture based on a new family of degradation functions [PDF]

open access: yes, 2017
Phase-field approaches to fracture based on energy minimization principles have been rapidly gaining popularity in recent years, and are particularly well-suited for simulating crack initiation and growth in complex fracture networks.

On the Lightweight Potential of Laser Additive Manufactured NiTi Triply Periodic Minimal Sheet Lattices

open access: yesAdvanced Engineering Materials, EarlyView.
This study explores the lightweight potential of laser additive‐manufactured NiTi triply periodic minimal surface sheet lattices. It systematically investigates the effects of relative density and unit cell size on surface quality, deformation recovery, compression behavior, and energy absorption.

Mechanical Properties and Reproducibility of One-Part Ambient-Cured Slag and Fly Ash-Based Geopolymer Concrete

open access: yesBuildings
The cement industry is a major source of anthropogenic CO2 emissions due to its energy-intensive production process and calcination of limestone. Producing one ton of cement emits approximately one ton of CO2, and cement accounts for about 5% to 8% of ...

Using fracture energy to characterize the hot mix asphalt cracking resistance based on the directtensile test

open access: yesRevista Facultad de Ingeniería Universidad de Antioquia, 2012
Cracking is currently one of the most common distresses in hot mix asphalt (HMA) pavements, often costing the highway agencies million of dollars in maintenance and rehabilitation activities.

Innovative Processing of Compacted Waste Aluminum Alloy Powders via Controlled Remelting and Solidification

open access: yesAdvanced Engineering Materials, EarlyView.
This study demonstrates an efficient recycling route for out‐of‐spec AlSi10Mg atomized powders through compaction and arc remelting followed by suction casting. By correlating compaction load, cooling rate, and resulting microstructure, we show that intermediate pressures (50–80 kN) and rapid cooling refine dendrites, reduce porosity, and enhance ...

Dissipative Visco-plastic Deformation in Dynamic Fracture: Tip Blunting and Velocity Selection

open access: yes, 2006
Dynamic fracture in a wide class of materials reveals "fracture energy" $\Gamma$ much larger than the expected nominal surface energy due to the formation of two fresh surfaces.

Zein‐Based Adhesives: Sustainable Extraction and Application in Bioadhesive Technologies

open access: yesAdvanced Engineering Materials, EarlyView.
Zein is extracted from corn gluten meal using a simple and scalable process with high yield (~90%). The resulting protein is applied in bioadhesives modified with Ca2+ and Fe3+ ions, exhibiting substrate‐dependent adhesion. The findings demonstrate competitive bonding performance and highlight the role of ionic interactions in tuning adhesion ...

DETERMINATION OF THE FRACTURE ENERGY AND THE FRACTURE RESISTANCE OF INTERFACES

open access: yesLe Journal de Physique Colloques, 1985
The basic concept and the fracture mechanics methods for determination of the fracture energy and the fracture resistance of interfaces between semi-brittle materials are reviewed. The interfacial fracture energy is derived from the global energy balance concept for crack propagations in an interface, whereas the fracture resistance parameter is based ...
