Morphogenesis02:19

Morphogenesis

30.6K
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 Deformations01:19

Plastic Deformations

497
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

492
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...

Main Methods:

  • Fabrication of elastomeric membranes embedded with inextensible textile mesh.
  • Utilizing a simple modeling approach for shape prediction and control.
  • Inflation-based transformation of 2D surfaces into target 3D shapes.

Main Results:

  • Achieved programmable transformation of 2D stretchable surfaces into target 3D shapes.
  • Synthetic tissues achieved target shapes within 10% accuracy.
  • Demonstrated imitation of natural textures like stone and plant shapes.

Conclusions:

  • The developed synthetic tissue groupings offer a novel method for controlled shape morphing in stretchable materials.
  • This biomimetic approach provides a foundation for advanced camouflage and adaptable surface technologies.
