Experimental and Numerical Modal Analysis of Composite Sandwich Structures Using Surfboards as Model Systems

open access: yesAdvanced Engineering Materials, EarlyView.
This article presents an experimental and numerical modal investigation of composite sandwich structures using surfboards as model systems. By comparing different core materials and reinforcement strategies, the study demonstrates how local stiffeners influence vibrational response and introduce characteristic modal features, highlighting modal ...

Grain Refinement During Severe Plastic Deformation and Similitude of Subgrain Formation: A Molecular Dynamics Study

open access: yesAdvanced Engineering Materials, EarlyView.
Molecular dynamics is used to investigate structure refinement during severe plastic deformation. The results show similitude with experimental data. Molecular dynamics simulations of severe plastic deformation of monocrystalline and polycrystalline samples by multiaxial compression of aluminum are carried out.

Particle Size Distributions

Journal of Aerosol Medicine and Pulmonary Drug Delivery, 2020
The distribution of particles sizes within an aerosol is essential information for understanding the behavior of that aerosol. The number of particles within certain size ranges is given by distributions specified by a count distribution if referring to number of particles, or a mass distribution if referring to particle mass. The cumulative number, or

Particle Size Distributions and Particle Size Alterations in Microemulsions

Journal of Pharmaceutical Sciences, 1984
Several component diagrams for different alcohols as cosurfactants and potassium oleate as the surfactant were investigated. Between the regions of the water-in-oil microemulsion and the micellar solution (reverse micelles), and diagrams showed a zone of instability which was determined by particle size analysis by means of photon correlation ...

Particle size distributions

Soil Science Society of America Journal, 2001
Conventional soil texture classification systems use different definitions of particle‐size distributions (PSDs). For example, sand in the International Soil Science Society (ISSS) system equals the combined separate limits of coarse silt and sand in the USDA system.

Comparison of the Particle Size Distribution

ATZautotechnology, 2003
Tests were carried out in order to determine the particle size distributions of several bus engines in the steady-state 13-mode test (ESC). The stoichiometric gas engines met the emission targets for EEVs and the expected Euro 5 standards for 2008.

Particle Size Distributions

1997
Particle sizes and particle size distributions are of both technical and scientific importance in emulsion polymerization systems On the technical side, particle sizes and particle size distributions are major determinants of a number of properties of a polymer latex, such as its viscoelastic behavior.

Particle Size Distribution

1994
The objectives of this test are: 1. Measure the distribution of sizes of particles in a ceramic raw material from its largest size DL ≈ 6700 lim (6.7 mm) to its smallest size D, ≈ 0.010 \μm. Unfortunately there is no single apparatus which is capable of measuring this range of sizes, common in the classical ceramic industry. Consequently, it may
