Experimental and numerical assessment of welding residual stress effects in a full-scale plate–truss composite steel girder joint

Welding residual stresses (WRS) are fabrication-induced initial stresses in welded steel joints and may influence local yielding and nonlinear stress redistribution. This study presents an experimental and numerical assessment of the effects of WRS in a full-scale integral lower-...

Boosting Energy Storage of AgNbO 3 ‐Based Capacitors by Constructing Low‐Atomic‐Displacement Region and M 2 ‐M 3 Two‐Phase Coexistence Strategy

ABSTRACT Dielectric capacitors with excellent energy‐storage performance are highly desirable for next‐generation advanced high/pulsed power capacitors that require miniaturization and integration. However, the low energy‐storage density arising from insufficient breakdown streng...
