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

Hydro-mechanical network modelling of particulate composites [PDF]
, 2017 Differential shrinkage in particulate quasi-brittle materials causes microcracking which reduces durability in these materials by increasing their mass transport properties.

A variational model of fracture for tearing brittle thin sheets [PDF]
, 2018 Tearing of brittle thin elastic sheets, possibly adhered to a substrate, involves a rich interplay between nonlinear elasticity, geometry, adhesion, and fracture mechanics.

Damage accumulation of bovine bone under variable amplitude loads
Bone 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 ...

Journal of Geophysical Research: Solid EarthIn the Earth's upper crust, rocks deform mostly by means of brittle fracturing processes. At the micro‐scale these processes involve the formation and growth of microcracks in the vicinity of defects such as open fissures, pores and other cavities. Large

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

Finite Element Modeling of Brittle and Ductile Modes in Cutting of 3C-SiC
Crystals, 2021 Machining of brittle ceramics is a challenging task because the requirements on the cutting tools are extremely high and the quality of the machined surface strongly depends on the chosen process parameters.

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