Innovating Aircraft Repair Processes: The Role of Digitalization in Sustainability
Advanced Engineering Materials, EarlyView.This research explores how digitalization—by storing detailed non‐destructive testing data in structured DICONDE databases and creating a standard data model of the component—innovates aviation maintenance and repair processes. Coupled with a developed state‐based simulation model, it enables data‐driven, sustainable repair strategies that reduce waste,

Winding Pressure of Lap Machine
Journal of the Textile Machinery Society of Japan - Transactions -, 1966 目的 フィニッシャスカッチャの前部にあるラップマシンのラップ巻き取り機構を明らかにし, その機構から生ずるラップ圧縮時のラップに加えられる圧力変化をストレインゲージ, スリップリング, オシログラフなどを使用して測定する.同時にラック上昇距離を測定してラップの平均厚さ, 圧縮角θの範囲などを求め, またラップの圧縮圧力曲線により巻き取り中のラップの挙動の模型的解析を行なう. 成果 1. ラップの平均厚さは0.15cmである。 (16oz/yd) 2. ラップ巻き取り中の圧縮角θの範囲は55～32°であり, これが圧力変化の原因となる. 3. ラップ巻き取り時の圧力は巻き始めでは圧力の変化速度が大きく, 巻き終わりに行くに従って小である.

What Do Large Language Models Know About Materials?
Advanced Engineering Materials, EarlyView.If large language models (LLMs) are to be used inside the material discovery and engineering process, they must be benchmarked for the accurateness of intrinsic material knowledge. The current work introduces 1) a reasoning process through the processing–structure–property–performance chain and 2) a tool for benchmarking knowledge of LLMs concerning ...
