A METHOD FOR FLUTTER DETECTION BY INFRARED IMAGING

A Method for Flutter Detection by Infrared Imaging

The performance enhancement of aircraft coupled with the development of increasingly lightweight and flexible materials has led designers to use smaller structural safety factors along the time, which can make aerodynamic surfaces more susceptible to aeroelastic phenomena, including flutter.This kind womens hats of occurrence must be carefully inve

Fragility Analysis of Concrete-Filled Steel Tubular Frame Structures with BRBs under Multiple Earthquakes Considering Strain Rate Effects

The fragility of concrete-filled steel tubular (CFST) frame structures with buckling-restrained braces (BRBs) subjected to multiple earthquakes is studied in this paper.First, a fiber beam element model with rate-dependent concrete and steel material properties is developed for CFST members and, then, the effect of the strain rate on the seismic re

Malacofauna of Crimea as a possible source of introductions to other regions of Ukraine: land snails of non-Crimean origin

Background.Due to global climate changes, a number of land mollusc species, previously known only from southern Ukraine or only from Crimea, are increasingly being recorded in different parts of the country.Apparently, not only species of the Crimean origin but also some other molluscs, native or alien to the Crimean Peninsula, could have been intr
