A Survey of Interlayer Interaction Models for Graphene and Other 2D Materials
Advanced Materials Interfaces, EarlyView.Van der Waals interactions arising from electronic polarization at atomically close interfaces generate corrugated interlayer energy landscapes that govern normal and tangential tractions. This review presents an overview of quantum, atomistic, analytical, and continuum modeling approaches, highlighting their roles across length scales in capturing ...

The mode-coupling of a stiff film/compliant substrate system in the post-buckling range
, 2015 A compressed stiff film/compliant substrate system undergoes a morphology transition from wrinkling to period-doubling. The perturbation method is used to obtain the approximate analytical solution incorporating both the quadratic and cubic ...

Micropillar‐Engineered Hybrid Adhesive Patch for Surface‐Conformable and Directional Adhesion
Advanced Materials Technologies, EarlyView.This work presents a surface‐conformable hybrid adhesive integrating height‐optimized hexagonal micropillars with open‐rectangular cuts. The micropillars enhance rough‐surface contact and microscale crack arrest, while the cuts guide and reverse interfacial cracks for strong and directional adhesion. The multiscale architecture achieves robust pull‐off

Doboku Gakkai Ronbunshu, 1998 軸圧縮力を受ける比較的厚肉の円筒殻は塑性域で最初, 座屈モードの局所化により軸対称のいわゆる提灯座屈が生ずるが, 変位制御で載荷を継続するとダイヤモンド座屈モードに変化することが実験的に観察されている. ここでは, 厳密な塑性分岐解析によりこのような塑性座屈モードの変化の過程を解析した. 解析結果として, ダイヤモンド座屈モードは, 軸対称座屈モードの局所化による提灯座屈発生後に塑性分岐により生ずること, 周方向の座屈波数は径厚比が大きいほど多いこと, さらに, ダイヤモンド型モードへの変化にともない局部的なひずみ集中度が大きく増加するため延性破壊による亀裂発生にもつながる可能性もあることなどが判明した.
