  • Poynting effect of brain matter in torsion 

    Balbi, Valentina; Trotta, Antonia; Destrade, Michel; Annaidh, Aisling Ni (Royal Society of Chemistry, 2019-06-13)
    We investigate experimentally and model theoretically the mechanical behaviour of brain matter in torsion. Using a strain-controlled rheometer, we perform torsion tests on fresh porcine brain samples. We quantify the torque ...
  • Tuning the pull-in instability of soft dielectric elastomers through loading protocols 

    Su, Y.P.; Chen, W.Q.; Destrade, Michel (Elsevier, 2019-03-22)
    Pull-in (or electro-mechanical) instability occurs when a drastic decrease in the thickness of a dielectric elastomer results in electrical breakdown, which limits the applications of dielectric devices. Here we derive the ...
