    Li, Jian; Slesarenko, Viacheslav; Rudykh, Stephan (Nature Research, 2022-05-02)

    Zhang, Quan; Rudykh, Stephan (Elsevier, 2022-04-28)
    We study the magneto-mechanical behavior of periodic laminates made of hard-magnetic active elastomers (HMAEs). We formulate the amended free-energy function for HMAEs, and derive an explicit expression for the induced ...

    Zhang, Quan; Cherkasov, Andrei V.; Arora, Nitesh; Hu, Gengkai; Rudykh, Stephan (Elsevier, 2023)
    We propose a magnetic field-induced asymmetric mechanical metamaterial. The tunable metamaterial integrates hard-Magnetic Active Elastomers (hMAEs) into the microstructural design combining snap-through, bi-stability, and ...

    We propose a design of a metamaterial for magnetically tunable propagation of nonlinear vector solitary waves. The metamaterial consists of a periodic array of units of hard-magnetic inclusion embedded in a soft matrix. ...
  • The Poynting effect 

    Zurlo, Giuseppe; Blackwell, James; Colgan, Niall; Destrade, Michel (American Association of Physics Teachers, 2020-11-19)
    Intuition suggests that twisting a cylinder will shorten it, but here it is shown that for a cylinder of an incompressible material, like rubber, twisting will always produce elongation.
  • Mechanical instability tuning of a magnetorheological elastomer composite laminate 

    Chen, Vincent W.; Arora, Nitesh; Goshkoderia, Artemii; Willey, Carson L.; Turgut, Zafer; Buskohl, Philip R.; Rudykh, Stephan; Juhl, Abigail T. (Elsevier, 2022-12-28)
    Magnetorheological elastomers (MRE) can change their shape and properties when activated by an external magnetic field. The attractive tunable properties of this stimuli-responsive composite can be further amplified by ...
  • Perspectives on allele-specific expression 

    Cleary, Siobhan; Seoighe, Cathal (Annual Reviews, 2021-04-28)
    Diploidy has profound implications for population genetics and susceptibility to genetic diseases. Although two copies are present for most genes in the human genome, they are not necessarily both active or active at the ...
  • The Varchenko determinant of a Coxeter arrangement 

    Pfeiffer, Götz; Randriamaro, Hery (De Gruyter, 2018)
    The Varchenko determinant is the determinant of a matrix defined from an arrangement of hyperplanes. Varchenko proved that this determinant has a beautiful factorization. It is, however, not possible to use this factorization ...
