Detection of tower bolt looseness and its influence of wind level [PDF]

open access: yesE3S Web of Conferences, 2021
Taking the wind turbine tower as the research object, based on the finite element software, a simplified beam-shell hybrid element model was first established; through the simulation, the phase difference between the loose position and the unloose ...

Scanning electron microscopy datasets for local fibre volume fraction determination in non-crimp glass-fibre reinforced composites

open access: yesData in Brief, 2021
The fatigue damage evolution depends on the local fibre volume fraction as observed in the co-submitted publication [1]. Conventionally, fibre volume fractions are determined as an averaged overall fibre volume fraction determined from small cuts of the ...

Semiempirical Models of Speedup Effect for Downburst Wind Field over 3-D Hills

open access: yesAtmosphere, 2023
Downbursts occur frequently in mountainous regions, such as the southwest of China, and causing extensive damage to engineering structures. While some researchers have developed semiempirical models for the speedup effect, most are based on the wind ...
