Over the past few years, soft materials and mechanical structures based on soft materials have driven our community into new exciting directions. Large deformations and instabilities of soft materials and structures can be immensely rich, albeit nontrivial. As a result, they offer unique opportunities to design multifunctional materials and devices with novel properties, through the appropriate design of material composition and structural layout. The mini-symposium will address recent experimental, computational, theoretical and manufacturing advances in this direction. Topics of particular interest include:

  • Electroactive and magnetoactive elastomers
  • Liquid crystal elastomers
  • Shape-memory and light-sensitive polymers
  • Responsive gels and Ionic Polymer-Metal Composites (IPMC)
  • Soft structures including rods, plates, shells and biological structures
  • Geometric and material instabilities
  • Foldable and deployable structures
  • 3D printing of soft materials and structures
