Influence of boundary conditions and geometric imperfections on lateral–torsional buckling resistance of a pultruded FRP I-beam by FEA [PDF]

, 2013
Presented are results from geometric non-linear finite element analyses to examine the lateral torsional buckling (LTB) resistance of a Pultruded fibre reinforced polymer (FRP) I-beam when initial geometric imperfections associated with the LTB mode ...

Surface and thermal load effects on the buckling of curved nanowires

Engineering Science and Technology, an International Journal, 2014
This paper investigates the impact of surface energy and thermal loading on the static stability of nanowires. We model nanowires as curved fixed–fixed Euler-Bernoulli beams and use Gurtin-Murdoch model to represent surface energy.

2D Abrupt Nano‐Junctions Blending sp–sp2 Bonds on Atomically Precise Heterostructures

Advanced Materials, EarlyView.
A lateral heterostructure between atomically precise sp–sp2$^2$ metalated graphdiyne and sp2$^2$ graphene nanoribbons is realized by on‐surface synthesis and investigated by STM and DFT. The impact of on‐surface synthesis byproducts on covalent junction formation yield is unveiled.

A Multifunctional Ionograsper Enabling Ion‐Redistribution Proximity Sensing and Structural‐Reconfiguration‐Driven Bidirectional Actuation

Advanced Materials, EarlyView.
A solid‐state ionic actuator integrates sensing, actuation, and memory within one material. A brief UV pulse induces long‐lasting deformation via coupled network rearrangement, dehydration, and rehydration, while ionic redistribution enables self‐powered sensing, supporting multifunctional, energy‐efficient soft robotic functions without continuous ...

A boundary element approach to buckling of laminated plates subjected to arbitrary in-plane loading [PDF]

, 2002
Laminated plate buckling is analyzed by the boundary element method (BEM). Ignoring bending stretching coupling, a solution is first sought for the membrane stresses due to arbitrary in plane loading.
