Asymptotic Behavior of an Elastic Satellite with Internal Friction [PDF]

open access: yesMathematical Physics, Analysis and Geometry, 2015
We study the dynamics of an elastic body whose shape and position evolve due to the gravitational forces exerted by a pointlike planet. The main result is that, if all the deformations of the satellite dissipate some energy, then under a suitable nondegeneracy condition there are only three possible outcomes for the dynamics: (i) the orbit of the ...

Variable Stiffness Flexure Structures Enabled by Phase‐Change Gallium and Adhesive Interfacial Locking for Soft Robotic Applications

open access: yesAdvanced Engineering Materials, EarlyView.
A flexure‐based variable stiffness structure is developed by integrating phase‐change modulation and adhesive interfacial locking of gallium. The design enables a wide stiffness variability, transitioning from soft, flexible behavior to rigid, load‐supporting performance.

Globalization of Corporate's Behavior and Friction

open access: yesContemporary Sociological Studies, 1995
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 ...

Towards Defect Phase Diagrams: From Research Data Management to Automated Workflows

open access: yesAdvanced Engineering Materials, EarlyView.
A research data management infrastructure is presented for the systematic integration of heterogeneous experimental and simulation data required for defect phase diagrams. The approach combines openBIS with a companion application for large‐object storage, automated metadata extraction, provenance tracking and federated data access, thereby supporting ...

Performance Analysis of Abradable Coating Systems for Aircraft Gas Turbines

open access: yesAdvanced Engineering Materials, EarlyView.
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.

Solid‐State Diffusion and Intermetallic Phase Formation in Roll‐Bonded Mg–Zn Composites With Kirigami‐Patterned Inlay

open access: yesAdvanced Engineering Materials, EarlyView.
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 Laminar Flow Model for the Pultrusion of Glass Fiber/Polyethylene Terephthalate Commingled Yarns

open access: yesAdvanced Engineering Materials, EarlyView.
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,

Dynamic Friction Behavior of Paper-Based Wet Friction Material Subjected to Contact Pressure Fluctuation

open access: yesTribology Online, 2012
In this research, dynamic friction behavior of paper-based wet friction material subjected to contact pressure fluctuation was investigated experimentally and theoretically. Complex friction coefficient obtained by the ratio between dynamic components of

Rafting of Ni‐Based Superalloys Under Multiaxial Load as Understood by Phase‐Field Simulations and Critical Experiments

open access: yesAdvanced Engineering Materials, EarlyView.
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.
