Energy transport and chaos in a one-dimensional disordered nonlinear stub lattice
Su Ho Cheong, Arnold Ngapasare, Vassos Achilleos +3
We investigate energy propagation in a one-dimensional stub lattice in the presence of both disorder and nonlinearity. In the periodic case, the stub lattice hosts two dispersive b…
Wave-packet spreading in disordered soft architected structures
Arnold Ngapasare, Georgios Theocharis, Olivier Richoux +2
We study the dynamical and chaotic behavior of a disordered one-dimensional elastic mechanical lattice which supports translational and rotational waves. The model used in this wor…
Chaos and Anderson Localisation in Disordered Classical Chains: Hertzian vs FPUT models
A. Ngapasare, G. Theocharis, O. Richoux +2
We numerically investigate the dynamics of an one-dimensional disordered lattice using the Hertzian model, describing a granular chain, and the Fermi-Pasta-Ulam-Tsingou model…
