Passive Morphing in Aerospace Composite Structures
Key Engineering Materials, 2021Attempts to add the advanced technologies to aerospace composite structures like fan blade have been on in recent times to further improve its performance. As part of these efforts, it has been proposed that the blade morph feasibility could be studied by building and optimizing asymmetric lay up of composite plies inside the blade which will help ...

Dynamic Modeling of Morphing Tensegrity Structures
Infotech@Aerospace 2011, 2011Tensegrity based structures represent a paradigm shift in the field of adaptive structures and are a technology enabler of growing importance. This control of tensegrity is a new field and the purpose of this effort is to develop the mathematical foundations of the non-linear dynamics and controls and demonstrate the validity on a proof-of-concept ...

Bistable morphing composite structures: A review
Thin-Walled Structures, 2019Abstract Bistable structures, a class of highly geometrically nonlinear morphing structures, have two stable configurations that remain in their respective equilibrium positions without the continuous application of an external force. This paper aims to summarise, review, and assess the literature about the theoretical studies, driving methods ...

Morphing Structures in the Venus Flytrap
2012Venus flytrap is a marvelous plant that intrigued scientists since times of Charles Darwin. This carnivorous plant is capable of very fast movements to catch insects. Mechanism of this movement was debated for a long time. Here, the most recent Hydroelastic Curvature Model is presented. In this model the upper leaf of the Venus flytrap is visualized as

Magnetothermal Shape‐Morphing of Thermoset Structures
Advanced Materials TechnologiesAbstractShape‐morphing of thermosets is challenging due to their permanently cross‐linked polymer network structure. Here, a magnetothermal shape‐morphing strategy is proposed for complex thermoset structures via reshaping, assembly, and shape memory. The thermoset composite is fabricated by adding magnetic nanoparticles into dynamically cross‐linked ...
