Lateral stability analysis of steel tapered thin-walled beams under various boundary conditions [PDF]
Numerical Methods in Civil Engineering, 2018 The lateral-torsional buckling of tapered thin-walled beams with singly-symmetric cross-section has been investigated before. For instance, the power series method has been previously utilized to simulate the problem, as well as the finite element method.

Effect of curvature on durable ice-phobic surfaces based on buckling metallic plates
Materials & Design, 2022 Degradation in system performance due to ice accretion on curved surfaces remains a decades-old challenge. We recently reported that Buckling Elastomer-like Anti-icing Metallic Surfaces (BEAMS) exhibit a low ice adhesion strength and extreme durability ...

Advanced Materials Technologies, EarlyView.A strain‐activated mechanical metamaterial is developed to achieve programmable dual‐phase stiffness through an intrinsic geometric locking mechanism. Finite element modeling and parametric analysis identify the key design parameters governing activation strain, stiffness transition, and energy absorption.

Advanced Science, EarlyView.Conventional single‐gradient freeze‐casting typically produces unidirectional porous architectures with limited transverse connectivity. The Sequential Hybridization by Infiltration and Freeze‐casting Technique (SHIFT) addresses this constraint by integrating secondary aligned structures within a preformed primary scaffold.
