Globalization of Corporate's Behavior and Friction
本稿は、一九八〇年代以降の日本の自動車産業の動向を事例に、わが国の企業行動の国際化の進展と現状をグローバル・ローカルモデルの視点から論じ、若干の展望をえることを目的にする。激しい貿易摩擦に直面した八〇年代、輸出型成長の限界を露呈した日本の自動車産業は、アメリカの中央部に巨大な「トランスプラント地帯」を形成し、新たな現地経営の段階をむかえている。本論では、まず、日本の自動車産業のグローバライゼーションを加速した輸出自主規制とアメリカへの工場進出の動向を概観する。次いで、アメリカ国内に出現した「ローカル空間」に着目し、立地段階から操業段階へと現地経営が進展していく過程で、日本のトランスプラントが直面するアメリカ国内の集団や組織、個人との間に生じる緊張や対立、葛藤や紛争を具体的に考察する。さらに ...

Performance Analysis of Abradable Coating Systems for Aircraft Gas Turbines
Three CoNiCrAlY/YSZ/MgAl2O4 abradable liner configurations on a nickel‐superalloy are evaluated by thermal‐gradient cycling and incursion tests. Laser ablation of the bondcoat and/or Y2O3‐stabilized ZrO2 (YSZ) intermediate layer increases mechanical interlocking and bonding for thick topcoats.

Contact dynamics from the atomic scale to nanostructured surfaces [PDF]
The collective mechanical behavior of a multitude of small contacts affects the friction between sliding bodies on the macroscopic scale. The contacts are complicated systems involving many atoms, which are constantly deformed, ruptured and reformed.

Mg–Zn composites with a thickness of 0.21 mm were fabricated using roll bonding of a kirigami‐patterned Mg alloy inlay within a Zn matrix. Thermal activation following this process led to the formation of tailored intermetallic structures, which provided the composite with enhanced flexural strength.

A simplified thermoplastic pultrusion model is developed to predict thermal fields in glass fiber/polyethylene terephthalate (GF/PET) composites with reduced computational cost. By combining effective material homogenization, validation against literature data, and Gaussian‐process‐based optimization, the study reveals how heating limits, pulling speed,

Phase‐field simulations coupled with dislocation‐density‐based crystal plasticity modeling reproduce γ′ rafting behavior in single‐crystal Ni‐based superalloys under varied loading conditions. The model captures both macroscopic creep and microscopic morphology evolution, with results matching high‐temperature creep experiments.

Shock isolation systems incorporating Coulomb friction
This study investigates a novel approach to the problem of shock isolation. The questions considered are whether friction produces a better performance in terms of reduced response during a shock compared to viscous damping and a lower residual response ...
