Numerical Simulations of Highly Porous Dust Aggregates in the Low-Velocity Collision Regime

, 2010
A highly favoured mechanism of planetesimal formation is collisional growth. Single dust grains, which follow gas flows in the protoplanetary disc, hit each other, stick due to van der Waals forces and form fluffy aggregates up to centimetre size.

Parametric Sensitivity of Shear Correction Factors for Multiwall Corrugated Structures

Materials
Transverse shear deformation plays a non-negligible role in lightweight periodic-core structures and motivates the use of shear-corrected reduced-order plate and beam models. However, the shear correction factor ks is often treated as a constant despite its strong dependence on cross-sectional heterogeneity and geometry. This work quantifies the global

A refined quasi-3D higher-order shear deformation theory for static, free vibration, and buckling of laminated composite plates on kerr-type foundation

Next Materials
Composite laminate plates are widely used in different engineering fields, yet existing higher-order shear theories (HSDTs) often fail to capture shear deformation and the coupled effects of elastic supports, leading to design inaccuracies.

A novel hyperbolic shear deformation beam theory for functionally graded nonlocal nanobeams

Discover Applied Sciences
This paper introduces an innovative nonlocal hyperbolic shear deformation theory for the bending, buckling, and vibration analysis of functionally graded (FG) nanobeams. The theory is developed based on a displacement field that accounts for both bending

Sources of contamination to weak lensing tomography: redshift-dependent shear measurement bias

, 2008
The current methods available to estimate gravitational shear from astronomical images of galaxies introduce systematic errors which can affect the accuracy of weak lensing cosmological constraints.

GaBoDS: The Garching-Bonn Deep Survey -- I. Anatomy of galaxy clusters in the background of NGC 300

, 2003
The Garching-Bonn Deep Survey (GaBoDS) is a virtual 12 square degree cosmic shear and cluster lensing survey, conducted with the WFI@2.2m MPG/ESO telescope at La Silla. It consists of shallow, medium and deep random fields taken in R-band in subarcsecond

Cylindrical bending of orthotropic plate strip based on nth-order plate theory

Journal of Materials and Engineering Structures, 2014
In this paper, cylindrical bending of orthotropic plates is presented using nth-order plate theory. Classical plate theory and parabolic shear deformation theory of Reddy can be considered as special cases of present theory.
