Material properties

  1. Modified Johnson-Cook model fits silicone adhesive high-strain-rate data
    Calibration and validation of Modified Johnson-Cook material models for silicone and epoxide adhesives under high strain rate loading using split-Hopkinson pressure bar testing.
  2. Several hyperelastic models matched tensile behavior of a thermoplastic elastomer
    Study evaluates hyperelastic and viscoelastic models for polyurethane thermoplastic elastomer to optimise hot plate welding simulations, finding strain rate effects require viscoelastic formulation.
  3. Outer-ligament design increases stiffness and broadens bandgaps
    Novel auxetic metamaterial designs with enhanced outer ligaments achieve 54.57% higher stiffness and broader elastic bandgaps, resolving traditional trade-offs through geometric optimization.
