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 ...
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 ...
Examination of the doping effects of samarium (Sm3+) and zirconium (Zr4+) on the photocatalytic activity of TiO2 nanofibers
(Elsevier, 2023)
Pure and samarium (Sm3+) - or zirconium (Zr4+)-doped TiO2 nanofibers were synthesized by electro-
spinning method followed by calcination at 500 °C for 1 h. As-spun fibers were smooth, straight and
continuous, whilst ...
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 ...
Antioxidant and cell-friendly Fe2TiO5 nanoparticles for food packaging application
(Elsevier, 2022)
An emerging technology of active packaging enables prolongation of food shelf life by limiting the oxygen transfer and the reactivity of free radicals, which both destruct food freshness. In this work, Fe2TiO5 nanoparticles ...
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 ...
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” ...
Trans-generational effect of cerium oxide-nanoparticles (nCeO2) on Chenopodium rubrum L. and Sinapis alba L. seeds
(CSIRO PUBLISHING, 2023)
Cerium oxide nanoparticles (nCeO2) are interesting nanomaterials due to their redox properties. Their wide application could result in unexpected consequences to environmental safety. Unlike acute toxicity, the trans-generational ...
