Two-dimensional vector bending sensor based on seven-core fiber Bragg gratings.

Optics Express, 2018
We demonstrated a two-dimensional vector-bending sensor by use of fiber Bragg gratings (FBGs) inscribed in a homogeneous seven-core fiber. Seven FBGs were simultaneously inscribed in each of all seven cores using a modified Talbot interferometer and a ...

Quality Enhancement of Laser Powder‐Bed Fusion Parts by Acoustically Assisted Additive Manufacturing by Laser Powder‐Bed Fusion and its Application to Lattice Structures

Advanced Engineering Materials, EarlyView.
Additive manufacturing technologies like laser powder‐bed fusion offer great design freedom and individualization of products down to a batch size of one. However, parts fabricated with this technology suffer from poor quality. Acoustic assistance during the build process can minimize these drawbacks.

Multimaterial Approach to Improve the Mechanical Properties of a Novel Modified Auxetic Reentrant Honeycomb Structure

Advanced Engineering Materials, EarlyView.
A multimaterial approach is introduced to improve upon auxetic structures by combining two different polymers into the same reentrant honeycomb structure via additive manufacturing. The deformation behavior as well as the resulting Poisson's ratio are thereby improved significantly.

Energy Dissipation in Nonlinearly Elastic Auxetic and Non‐Auxetic Mechanical Metamaterials with Friction and Material Damping

Advanced Engineering Materials, EarlyView.
This study presents a hyperelastic mechanical metamaterial for elastic energy dissipation. Energy is dissipated within its unit cells by friction assisted by material damping. Frictional contact is enhanced when using auxetic unit cells. The load–displacement plot for one compression cycle shows a pronounced hysteresis loop, indicating that a large ...
