It is of great importance to quantify the seismic damage reinforced concrete (RC) short columns since they often experience severe due likely excessive shear deformation. In this paper, quantification method RC under earthquakes proposed based on crack images and enhanced U-Net. To end, short-column specimens were prepared tested cyclic loading. The force-displacement hysteresis curves obtained quantitatively calculate indicator column energy criterion. At same time, surfaces taken by...
Corrugated damage to bearings is a common fault in electrical facilities such as new energy vehicles, wind power, and high-speed railways. The aim of this article reveal the microscopic characteristics formation mechanism damages. corrugation with alternating “light” “dark” shape was produced on GCr15 bearing races experimental conditions. Compared light area, dark area (in images generated by optical microscope) has more severe erosion, lower hardness, concave morphology, oxidation. As...
Textured surfaces have been widely applied in the field of engineering for friction reduction, but research on effects different texture design parameters wear and fatigue resistance bearing steel remains insufficiently explored. In order to improve anti-wear anti-fatigue performance prolong service life steel, surface texturing technology was fabricate textured GCr15 materials. this work, micro-groove designed by hydrodynamic theory, then, it fabricated using nanosecond laser processing....
Abstract The slamming load acting on the bow of a large-bow flare ship is equivalent to moving pulse time history with linear rise and exponential attenuation. Abaqus finite element software used study elastic dynamics multiple stiffened plates under action load. Response calculations are conducted analyze influence different parameters dynamic response plate. stress coefficient DLFps (Dynamic Load Factor plate stress) introduced, change pattern sensitivity between dimensionless analyzed,...
ABSTRACT Fretting damage failure analysis of a Chinese carbon railway axle RD 2 was carried out. The wheel hub in situ cut to expose the damaged surface seat avoid additional damage. A small‐scale test rig developed, and simulation tests were performed at different rotator speeds 1800 2100 rpm. wear mechanism fretting areas combination abrasive wear, oxidative delamination. fracture surfaces exhibited characterization multisource step‐profile. fatigue crack initiated subsurface propagated...
The electrical transmission between moving parts requires contact pairs such as rolling rings, sliding connectors, etc. These functional can be defined current-carrying frictional because they need to bear the of current while enduring friction and wear. rough are typical surface withstands load force, heat, electricity, resulting in unique characteristics pair. research progress tribology has been reviewed this paper. correlation mechanism tribological performance summarized. composite...
As a maskless nanofabrication technique, friction-induced selective etching can easily produce nanopatterns on Si(100) surface. Experimental results indicated that the height of increased with KOH time, while their width scratching load. It has also found contact pressure 6.3 GPa is enough to fabricate mask layer To understand mechanism involved, cross-sectional microstructure scratched area was examined, and ability tip-disturbed silicon studied. Transmission electron microscope observation...
Polyether ether ketone (PEEK) is one of the representatives special engineering plastics. Due to high molding temperature, method ordinary plastics and cavity abrasives are difficult meet requirements. In view this, pure PEEK was prepared by vacuum hot pressing sintering technology at different temperatures. The mechanical properties microstructure characterization results showed that 350 °C excellent friction wear properties. Then CF/PEEK composites were optimum temperature. experiments...
