Size and shape effect of specimen on the compressive strength of HPLWFC reinforced with glass fibres

open access: yesJournal of King Saud University: Engineering Sciences, 2017
High performance lightweight foamed concrete (HPLWFC) have a structural strength with low density and high flowability. HPLWFC is used in modern concrete technology and extensively in the construction applications of high-rise buildings, long-span ...

Quantum-to-classical crossover in the spin glass dynamics of cavity QED simulators

open access: yesPhysical Review Research
By solving the quench dynamics of a frustrated many-body spin-boson problem, we investigate the role of spin size on the dynamical formation of spin-glass order. In particular, we observe that quantum and classical spin glasses exhibit markedly different

Possible Ergodic-nonergodic regions in the quantum Sherrington-Kirkpatrick spin glass model and quantum annealing

open access: yes, 2018
We explore the behavior of order parameter distribution of quantum Sherrington-Kirkpatrick model in the spin glass phase using Monte Carlo technique for the effective Suzuki-Trotter Hamil- tonian at finite temperatures and that at zero temperature ...

Confinement effects on glass forming liquids probed by DMA

open access: yes, 2010
Many molecular glass forming liquids show a shift of the glass transition T-g to lower temperatures when the liquid is confined into mesoporous host matrices.

Size-dependent radiative cooling power of glass-polymer metafilms

open access: yesMaterials & Design
Glass-polymer metamaterial, in which glass microspheres are randomly distributed in a polymer matrix, has been demonstrated to be a highly efficient daytime radiative cooling material that can be manufactured via roll-to-roll processes at scale and at ...

Glass breaking strength: The role of surface flaws and treatments [PDF]

open access: yes
Although the intrinsic strength of silicon dioxide glass is of the order of 10 to the 6th power lb/sq in, the practical strength is roughly two orders of magnitude below this theoretical limit, and depends almost entirely on the surface condition of the ...

Rate-Dependent Avalanche Size in Athermally Sheared Amorphous Solids

open access: yes, 2009
We perform an extensive numerical study of avalanche behavior in a 2D LJ glass at T=0, sheared at finite strain rates $\dot\gamma$. From the finite size analysis of stress fluctuations and of transverse diffusion we show that flip-flip correlations ...

Critical exponents in Ising spin glasses

open access: yes, 1997
We determine accurate values of ordering temperatures and critical exponents for Ising Spin Glass transitions in dimension 4, using a combination of finite size scaling and non-equilibrium scaling techniques.

Overlap Among States at Different Temperatures in the SK Model

open access: yes, 2002
We discuss the issue of temperature chaos in the Sherrington--Kirkpatrick spin glass mean field model. We numerically compute probability distributions of the overlap among (equilibrium) configurations at two different values of the temperature, both in ...

Structural properties of a calcium aluminosilicate glass from molecular-dynamics simulations: A finite size effects study

open access: yes, 2004
We study a calcium aluminosilicate glass of composition (SiO$_2$)$_{0.67}$-(Al$_2$O$_3$)$_{0.12}$-(CaO)$_{0.21}$ by means of molecular-dynamics (MD) simulations, using a potential made of two-body and three-body interactions.
