Crushing Performance of Ultra-Lightweight Foam Concrete with Fine Particle Inclusions

open access: yesApplied Sciences, 2019
Foam concrete is a low-density controlled strength material that can potentially be used for accommodating different types of particles—recycled fine aggregate being an example.

Deep anterior lamellar keratoplasty in the management of keratoconus

open access: yesIndian Journal of Ophthalmology, 2013
Advanced cases of keratoconus often require surgical intervention to restore corneal anatomy and improve eyesight. Penetrating keratoplasty (PK) although commonly performed has potential risk of immunological rejection and is now no longer automatically ...

Effective Elastic Modulus of Wavy Single-Wall Carbon Nanotubes

open access: yesC, 2023
A simple method for determining the effective elastic modulus of wavy single-wall carbon nanotubes (SWCNTs) is presented in this paper. The effective modulus of curved SWCNTs is derived using Castigliano’s theorem.

Use of Vibrational Optical Coherence Tomography to Analyze the Mechanical Properties of Composite Materials

open access: yesSensors, 2021
Energy storage and dissipation by composite materials are important design parameters for sensors and other devices. While polymeric materials can reversibly store energy by decreased chain randomness (entropic loss) they fail to be able to dissipate ...

Effects of particle distribution on mechanical properties of magneto-sensitive elastomers in a homogeneous magnetic field

open access: yesCondensed Matter Physics, 2012
We propose a theory which describes the mechanical behaviour of magneto-sensitive elastomers (MSEs) under a uniform external magnetic field. We focus on the MSEs with isotropic spatial distribution of magnetic particles.
