This paper investigates the fatigue upgrading of typical cover plate joint connections in existing steel bridge girders through cover plate extension. The upgraded detail is created by removing the existing transverse end weld, then welding the extension t ...
Quantification of chemical toxicity in small-scale bioassays is challenging owing to small volumes used and extensive analytical resource needs. Yet, relying on nominal concentrations for effect determination maybe erroneous because loss processes can sign ...

Hindu Kush Himalaya constitutes headwater of some of the largest transboundary basins of planet that sustain one-fourth global population dependent primarily on subsistence agriculture in South Asia. Climate change has stressed hydrological regimes of Hima ...

In modern automated assembly lines, part feeders play an important role to separate and sort parts. Agility and flexibility are required to achieve a good yield for different types of parts. The common working principle is to vibrate a working plate driven ...
The invention concerns a light filter comprising a plate defined by a length along a direction x, a width along a direction y and a height along a direction z said plate including at least one chamber containing Liquid Crystals (LC) molecules and which is ...

In the current trend toward thicker aluminium plates, a major concern is the generation of high internal stresses during quenching, which can cause distortions during machining and pose serious safety concerns. Although the material is stretched after quen ...

The association of experimental data showing that the plastic deformation of olivine, the main constituent of the upper mantle, is highly anisotropic and the ubiquitous seismic anisotropy in the upper mantle, which indicates that olivine crystals show cohe ...

A numerical model of the medial open wedge tibial osteotomy based on the finite element method was developed. Two plate positions were tested numerically. In a configuration, (a), the plate was fixed in a medial position and (b) in an anteromedial position ...
Earthquakes occur on planar faults that often mark the boundaries between tectonic plates that collide or slide against each other. During an earthquake, sudden slip on the fault releases elastic energy stored in the earth's crust or upper mantle, resultin ...
The influence of material heterogeneities is studied in the context of dynamic failure. We consider a pre-strained plate problem, the homogeneous case of which has been widely studied both experimentally and numerically. This setup is used to isolate the e ...
