Planar structured materials with extreme elastic anisotropy

Kavli Affiliate: Chiara Daraio | First 5 Authors: Jagannadh Boddapati, Chiara Daraio, , , | Summary: Designing anisotropic structured materials by reducing symmetry results in unique behaviors, such as shearing under uniaxial compression or tension. This direction-dependent coupled mechanical phenomenon is crucial for applications such as energy redirection. While rank-deficient materials such as hierarchical laminates […]
