Optimal design of composite granular protectors (2008)
Fraternali, Fernando, Porter, Mason A., Daraio, Chiara
We employ an evolutionary algorithm to investigate the optimal design of composite protectors using one-dimensional granular chains composed of beads of various sizes, masses, and stiffnesses. We...
