Sealing Failure Behavior of Metal‐Sealed Bolted Flange Connections Under Cyclic Loading

ABSTRACT Metal‐sealed bolted flange connections are critical in well‐control surface facilities, where cyclic loads may induce bolt loosening, leakage, and sealing failure. This study investigated the failure behavior of 6BX metal‐sealed flange connections under cyclic loading us...

A Flexible Bimodal Sensor With Single Configuration Enabling Strain and Touchless Sensing

ABSTRACT Human–machine interfaces increasingly require sensors capable of perceiving both direct physical interactions and remote environmental cues. However, existing multimodal flexible sensors typically rely on physically separated sensing units and complex signal integration,...

Compression failure analysis of composite grid-stiffened structures: Effects of skin layup schemes and grid layout configurations

Advanced grid-stiffened (AGS) composite structures are widely used in aerospace engineering due to their excellent specific strength and high damage tolerance. Previous studies have predominantly focused on the optimization of grid stiffener configurations, while the effects of s...
