The internal structure and composition of a plate-boundary-scale serpentinite shear zone: the Livingstone Fault, New Zealand [PDF]

open access: yesSolid Earth, 2019
Deciphering the internal structure and composition of large serpentinite-dominated shear zones will lead to an improved understanding of the rheology of the lithosphere in a range of tectonic settings.

Influence of section depth on the structural behaviour of reinforced concrete continuous deep beams [PDF]

open access: yes, 2007
YesAlthough the depth of reinforced concrete deep beams is much higher than that of slender beams, extensive existing tests on deep beams have focused on simply supported beams with a scaled depth below 600 mm.

Analytical solution of two-layer beam taking into account interlayer slip and shear deformation [PDF]

open access: yes, 2007
A mathematical model is proposed and its analytical solution derived for the analysis of the geometrically and materially linear two-layer beams with different material and geometric characteristics of an individual layer.

Sheared force-networks: anisotropies, yielding and geometry [PDF]

open access: yes, 2005
A scenario for yielding of granular matter is presented by considering the ensemble of force networks for a given contact network and applied shear stress $\tau$.

Shear testing of steel fiber reinforced expanded-shale lightweight concrete beams with varying of shear-span to depth ratio and stirrups

open access: yesCase Studies in Construction Materials, 2021
Aiming at achieving the beneficial effects from the lightened self-weight of structures, steel fiber reinforced expanded-shale lightweight concrete (SFRELC) is promoting to be applied in structural engineering.

Heavy snowfall event over the Swiss Alps: did wind shear impact secondary ice production? [PDF]

open access: yesAtmospheric Chemistry and Physics, 2023
The change in wind direction and speed with height, referred to as vertical wind shear, causes enhanced turbulence in the atmosphere. As a result, there are enhanced interactions between ice particles that break up during collisions in clouds which could

On sixfold coupled vibrations of thin-walled composite box beams [PDF]

open access: yes, 2008
This paper presents a general analytical model for free vibration of thin-walled composite beams with arbitrary laminate stacking sequences and studies the effects of shear deformation over the natural frequencies.

Tidal wind shear observed by meteor radar and comparison with sporadic E occurrence rates based on GPS radio occultation observations [PDF]

open access: yesAdvances in Radio Science, 2019
We analyze tidal (diurnal, semidiurnal, terdiurnal, quarterdiurnal) phases and related wind shear in the mesosphere/lower thermosphere as observed by meteor radar over Collm (51.3∘ N, 13.0∘ E).

Transient conduit permeability controlled by a shift between compactant shear and dilatant rupture at Unzen volcano (Japan) [PDF]

open access: yesSolid Earth, 2022
The permeability of magma in volcanic conduits controls the fluid flow and pore pressure development that regulates gas emissions and the style of volcanic eruptions.

Analysis of fracture processes in reinforced concrete beams without stirrups

open access: yesFracture and Structural Integrity, 2021
The analysis of fracture processes which led to shear failure in reinforced concrete beams without transverse reinforcement was performed on the basis of test results from the author’s own experimental investigation and numerical simulations.
