A scaling approach to size effect modeling of J(c) CDF for 20MnMoNi55 reactor steel in transition temperature region
(Elsevier, 2022)
Ever since the 1980s there is a sustained interest in the size effect, as one of the most pronounced consequences of fracture mechanics. In the present study, the investigation of the size effect is focused on estimation ...
Ordering effect of kinetic energy on dynamic deformation of brittle solids
(Elsevier, 2008)
The present study focuses on the plane strain problem of medium-to-high strain-rate loading of an idealized brittle material with random microstructure. The material is represented by an ensemble of “continuum particles” ...
Some Observations Regarding Stochasticity of Dynamic Response of 2D Disordered Brittle Lattices
(SAGE Publications, 2011)
It had been long recognized that the tensile strength of brittle materials
increases with increase of the loading rate. In the present article, a statistical
approach to rupture of a disordered 2D triangular truss lattice ...
On strain-rate sensitivity and size effect of brittle solids: transition from cooperative phenomena to microcrack nucleation
(Springer Nature, 2013)
An idealized brittle microscale system is subjected to dynamic uniaxial tension in the medium-tohigh
strain-rate range (˙ε ∈ [100 s−1, 1×107 s−1]) to investigate its mechanical response under constrained
spatial and ...
Impact fragmentation of nanoscale projectiles at ultrahigh striking velocities
(Springer Nature, 2015)
Molecular-dynamics simulations of the
classic Taylor experiment are performed to investigate
some general trends of impact fragmentation at ultrahigh
striking velocities. The striking velocities of flatended,
monocrystalline, ...
Further Remarks on Stochastic Damage Evolution of Brittle Solids Under Dynamic Tensile Loading
(SAGE Publications, 2011)
This article illuminates some general features and provides elementary
interpretations of the deformation, damage, and failure of brittle solids characterized
by very low fracture energy. The dynamic response of these ...
Metal oxide nanoparticles for safe active and intelligent food packaging
(Elsevier Science London, London, 2021)
Background: Food safety and food security remain the major concern of consumers and the food industry. Bacterial contamination continues to be a crucial food safety issue. Smart packaging incorporates both active and ...
The Krajcinovic approach to model size dependent fracture in quasi-brittle solids
(Elsevier, 2014)
The failure in “quasibrittle” microstructural systems, occurring with no early warning, is a debated problem of great practical importance for the structural engineering community. Available models do not fully account for ...
A Note on Short-time Response of Two-dimensional Lattices during Dynamic Loading
(SAGE Publications, 2008)
The disordered 2D lattices are used extensively to study damage
evolution and fracture of inhomogeneous or multi-phase systems. The present note
addresses their initial elastic response during dynamic loading. Namely, a ...
Damage-fragmentation transition: Size effect and scaling behavior for impact fragmentation of slender projectiles
(SAGE Publications, 2018)
The focus of the present article is on the size effect of a transition region from the damaged to the fragmented phase in impact-induced breakup of a slender projectile. Molecular dynamics simulations of the classic ballistic ...
