Influence of matrix toughness and interfacial strength on the toughness of epoxy composites with ductile steel fabric reinforcement [PDF]

open access: yes, 2015
In the last decades, several studies have been performed on polymers reinforced with steel cords or wires. However, the diameter of these steel reinforcements was still quite large (200 micron and more).

Implementation of the Quasi-Brittle Damage Model for 2024 Aluminum Alloy under Periodic Loading [PDF]

open access: yesInternational Journal of Advanced Design and Manufacturing Technology, 2019
Damage mechanics is one of the most important parts of mechanical engineering that determines the time life for different mechanical elements. The most various models that have been provided so far in damage mechanics, are related to ductile or brittle ...

Hydro-mechanical network modelling of particulate composites [PDF]

open access: yes, 2017
Differential shrinkage in particulate quasi-brittle materials causes microcracking which reduces durability in these materials by increasing their mass transport properties.

Mesomechanics coal experiment and an elastic-brittle damage model based on texture features

open access: yesInternational Journal of Mining Science and Technology, 2017
To accurately describe damage within coal, digital image processing technology was used to determine texture parameters and obtain quantitative information related to coal meso-cracks.

Damage accumulation of bovine bone under variable amplitude loads

open access: yesBone Reports, 2016
Stress fractures, a painful injury, are caused by excessive fatigue in bone. This study on damage accumulation in bone sought to determine if the Palmgren-Miner rule (PMR), a well-known linear damage accumulation hypothesis, is predictive of fatigue ...

Damage and dissipation mechanisms in the dynamic fracture of brittle materials: Velocity driven transition from nominally brittle to quasi-brittle

open access: yesEPJ Web of Conferences, 2010
We present the results of recent dynamic fracture experiments [Scheibert et al., Phys. Rev. Lett. 104 (2010) 045501] on polymethylmethacrylate, the archetype of nominally brittle materials, over a wide range of crack velocities.

A robust numerical framework for the analysis of material failure of fibre reinforced soft tissue [PDF]

open access: yes, 2011
In this work, robustness and stability of continuum damage models applied to material failure in soft tissues are addressed. In the implicit damage models equipped with softening, the presence of negative eigenvalues in the tangent ...

Truss-like Discrete Element Method Applied to Damage Process Simulation in Quasi-Brittle Materials

open access: yesApplied Sciences, 2023
This paper discusses the combined application of the lattice discrete element method (LDEM) and the acoustic emission (AE) technique to analyze damage in quasi-brittle materials.

Neutron emissions in brittle rocks during compression tests: Monotonic vs cyclic loading

open access: yes, 2010
Neutron emission measurements, by means of 3He devices and neutron bubble detectors, were performed during two different kinds of compression tests on brittle rocks: (i) under displacement control, and (ii) under cyclic loading. The material used for the

A variational model of fracture for tearing brittle thin sheets [PDF]

open access: yes, 2018
Tearing of brittle thin elastic sheets, possibly adhered to a substrate, involves a rich interplay between nonlinear elasticity, geometry, adhesion, and fracture mechanics.
