  • Zero-porosity NPR structure and tuning of NPR structure for particular localities
    Patent number: 10843505
    Abstract: The present concepts include a zero-porosity structure having a plurality of structural elements arranged to provide a negative Poisson's ratio and, further, a new mechanism to generate negative Poisson's ratio is single material, zero-porosity structure.
    Type: Grant
    Filed: January 9, 2016
    Date of Patent: November 24, 2020
    Assignees: President and Fellows of Harvard College, Siemens Canada Limited
    Inventors: Katia Bertoldi, Fabian Enrique Sanchez Guerrero, Matthew Christopher Innes, Farhad Javid, Minh Quan Pham, Megan Schaenzer, Sr., Ali Shanian, Evelyne Smith-Roberge
  • Hybrid dimple-and-void auxetic structures with engineered patterns for customized NPR behavior
    Patent number: 10603866
    Abstract: Auxetic structures, low porosity auxetic sheets, systems and devices with auxetic structures, and methods of using and methods of making auxetic structures are disclosed. An auxetic structure is disclosed which includes an elastically rigid body with a plurality of apertures extending through the elastically rigid body and a plurality of protrusions projecting from the elastically rigid body. The apertures and protrusions are arranged in an engineered pattern, such as an array of rows and columns. The apertures are cooperatively configured with the protrusions to provide a predefined porosity while exhibiting stress reduction through negative Poisson's Ratio (NPR) behavior under macroscopic planar loading conditions. In some embodiments, the protrusions, which are elliptical or semispherical dimples, are interposed in square or hexagonal patterns with the apertures, which are S-shaped through slots or circular boreholes.
