Preform architectures effect on laser ablative behavior of C/SiC–Ti3SiC2 composites

Te Ma, Wenqi Du, Ruixing Wang, Cheng Qiu et autres

In this work, the effect of preform architecture on the ablative behavior of C/SiC–Ti 3 SiC 2 composites is investigated. Two-dimensional laminated (2D) and three-dimensional needled (3DN) architectures are fabricated and subjected to laser ablation experiments and characterization. A phenomenological multi-scale ablation …

Comp-Enabled URLLC Availability Analysis with NR Protocols

Wu Yuan, Ling Liu, Yiqing Zhou, Jinglin Shi

Ultra-reliable and low-latency communication (uRLLC) is an important feature for the fifth-generation mobile network and beyond ($\mathbf{5 G} \boldsymbol{/} \mathbf{B 5 G}$). It has stringent requirements for ultra-high reliability (e.g., 1e-5) and extremely low user plane latency (e.g., 1ms). For cell edge …

Load-bearing advantage space of pyramid lattice sandwich cylinder under the constraints of multi-failure modes based on thin-shell assumptions

Shuai Kang, Hongwei Song, Wu Yuan

Pyramid lattice sandwich cylinders (LSCs) exhibit remarkable structural efficiency, yet local failures can significantly reduce their load-bearing capacity. This study investigates the load-bearing capability of pyramid LSCs relative to single-walled shells (SSs) of equivalent size and mass under multi-failure modes. A multi-failure …
