The mechanics of composite corrugated structures: A review with applications in morphing aircraft [PDF]

, 2015
Corrugation has long been seen as a simple and effective means of forming lightweight structures with high anisotropic behaviour, stability under buckling load and energy absorption capability.

Conceptual-level evaluation of a variable stiffness skin for a morphing wing leading edge [PDF]

, 2019
A morphing leading edge produces a continuous aerodynamic surface that has no gaps between the moving and fixed parts. The continuous seamless shape has the potential to reduce drag, compared to conventional devices, such as slats that produce a discrete

Simplified 2D Skin Lattice Models for Multi-Axial Camber Morphing Wing Aircraft

Aerospace, 2019
Conventional fixed wing aircraft require a selection of certain thickness of skin material that guarantees structural strength for aerodynamic loadings in various flight modes.

Gaussian-preserved, non-volatile shape morphing in three-dimensional microstructures for dual-functional electronic devices

Nature Communications, 2021
Designing the functional diversification of electronic devices with morphable 3D structures in multistable states remains a challenge. Here, the authors present a Gaussian-preserved shape-morphing system to realize ultrafast shape morphing and non ...

3D Printed Shape Memory Polymers Produced via Direct Pellet Extrusion

Micromachines, 2021
Shape memory polymers (SMPs) are materials capable of changing their structural configuration from a fixed shape to a temporary shape, and vice versa when subjected to a thermal stimulus.

Compliant morphing structures from twisted bulk metallic glass ribbons [PDF]

, 2020
In this work, we investigate the use of pre-twisted metallic ribbons as building blocks for shape-changing structures. We manufacture these elements by twisting initially flat ribbons about their (lengthwise) centroidal axis into a helicoidal geometry ...

Effects of dynamical chordwise retracting and stretching on the propulsive performance of a pure plunging flat plate

AIP Advances, 2023
An innovative morphing scheme, i.e., dynamical chordwise retracting and stretching, has been proposed for flapping wings. Its aerodynamic effects have been investigated based on a plunging two-dimensional flat wing.

Ensemble representation of uncertainty in Lagrangian satellite rainfall estimates [PDF]

, 2013
A new algorithm called Lagrangian Simulation (LSIM) has been developed that enables the interpolation uncertainty present in Lagrangian satellite rainfall algorithms such as the Climate Prediction Center (CPC) morphing technique (CMORPH) to be ...

Cryo-EM map interpretation and protein model-building using iterative map segmentation. [PDF]

, 2020
A procedure for building protein chains into maps produced by single-particle electron cryo-microscopy (cryo-EM) is described. The procedure is similar to the way an experienced structural biologist might analyze a map, focusing first on secondary ...

Assessment criteria for 2D shape transformations in animation [PDF]

, 1997
The assessment of 2D shape transformations (or morphing) for animation is a difficult task because it is a multi-dimensional problem. Existing morphing techniques pay most attention to shape information interactive control and mathematical simplicity ...
