To assess mixture dispersibility, a Fast Screening Impactor (FSI) (Copley Scientific, UK) and a low resistance ScreenHaler device (Thalberg et al. 2016) were used. The volumetric rate of airflow was set to 60 ± 0.3 L/min and the suction time to 4 s (4 L total suction volume) using...
etc., under the premise of ensuring that the mechanical and corrosion resistance meet the requirements, they also meet the requirements of the weld seam for low temperature impact toughness; For the 3 types of the welding
according to the "Atmospheric corrosion resistant steel and stainless steel welding materials for railway vehicles (TB/T2374-2008)" and other standards for process evaluation and periodic infiltration corrosion test, its mechanical properties, atmospheric corrosion resistance, ...
Table2illustrates the ultimate FRP Strain (Ɛfu), the maximum FRP strain for the EB-strengthened beam under flexural (Ɛm), and the efficiency of the strengthening elements. After the steel rebar yielded, two factors enhanced the load resistance (increasing the strain in the FRP laminates an...
The SSW processes which use the joule heat like resistance welding but control the interface temperature below the melting point. (3) And the SSW processes, i.e., soldering and brazing, where the parent metals are in solid state during welding. Owing to the solid state characteristic of the...
The first is that the pair of functions is “collapsing”, a notion introduced by Unruh in his investigations of collision-resistance against quantum attacks. In our context this property implies that it is computationally hard to distinguish between an arbitrary superposition over preimages, as in...
MEASURING TIRE FRICTION UNDER SLIP WITH THE PENN STATE ROAD FRICTION TESTER SKID RESISTANCE MEASUREMENTS REMAIN THE MOST PRACTICAL METHOD FOR CHARACTERIZING THE FRICTIONAL PROPERTIES OF HIGHWAY PAVEMENTS. FRICTION MEASUREMENTS WITH... H Domandt,WE Meyer - 《Highway Research Record》 被引量: 6发表: ...
Zhang et al. (2019) claimed that the fatigue performance of OSDs is controlled by the governing fatigue cracking model among the multiple cracking models. On this basis, the high fatigue resistance OSD (LI et al.2019) is proposed, which has the configuration innovation at both the rib-to-de...
To consider the disordering-induced instabilities in crystals more directly (and quantitatively), we need to establish the mechanical properties of a crystalline material, that determine its resistance towards deformation or fracture. Interestingly, the answer to the question that which out of several ...
