Morphogenesis

Morphogenesis

Plant morphogenesis—the development of a plant’s form and structure—involves several overlapping developmental processes, including growth and cell differentiation. Precursor cells differentiate into specific cell types, which are organized into the tissues and organ systems that make up the functional plant.

Plastic Deformations

Plastic Deformations

Plastic deformation represents a fundamental concept in materials science, which explains the irreversible change in the shape of a material when it experiences stress beyond its elastic capability. This phenomenon is important in structural engineering, especially in designing and analyzing cantilever beams—structures that are securely fixed at one end and bear loads at the opposite end. When these beams are subjected to loads within their elastic range, they will return to their...

Plastic Deformations

Plastic Deformations

It is essential to understand how structural members behave under plastic deformation when the bending stress exceeds the material's yield strength. This state of deformation permanently alters the shape of the member, in contrast to the linear elastic behavior observed before yielding. The strain at any point in the member is expressed in terms of maximum strain. Notably, the neutral axis, which coincides with the centroid during elastic bending, shifts away from the centroid under plastic...

Para imitar la capacidad natural de los cefalópodos para cambiar rápidamente la textura de la piel.

Principales métodos:

Fabricación de membranas de elastómero incrustadas con una malla textil inextensible.
Utilizando un enfoque de modelado simple para la predicción y el control de la forma.
Transformación basada en la inflación de superficies 2D en formas 3D objetivo.

Principales resultados:

Se ha conseguido la transformación programable de superficies 2D estirables en formas 3D objetivo.
Los tejidos sintéticos lograron las formas objetivo con una precisión del 10%.
Imitación demostrada de texturas naturales como la piedra y las formas de las plantas.

Conclusiones:

Las agrupaciones de tejido sintético desarrolladas ofrecen un nuevo método para la transformación controlada de la forma en materiales elásticos.
Este enfoque biomimético proporciona una base para el camuflaje avanzado y las tecnologías de superficie adaptables.
