Optimal Design of Layered Periodic Composites for Mitigation of Impact-Induced Elastic Waves
Hossein Sadeghi, Sia Nemat-Nasser
A systematic method for optimal design of layered periodic composites for mitigation of impact-induced shock waves is presented. Frequency spectrum of a pulse with a sharp rise-tim…
On the Limit and Applicability of Dynamic Homogenization
Ankit Srivastava, Sia Nemat-Nasser
Recent years have seen considerable research success in the field of dynamic homogenization which seeks to define frequency dependent effective properties for heterogeneous composi…
Mixed-variational formulation for phononic band-structure calculation of arbitrary unit cells
Ankit Srivastava, Sia Nemat-Nasser
This paper presents phononic band-structure calculation results obtained using a mixed variational formulation for 1-, and 2-dimensional unit cells. The formulation itself is prese…
Anti-plane Shear Waves in Layered Composites: Band Structure and Anomalous Wave-refraction
Sia Nemat-Nasser
For oblique anti-plane shear waves in periodic layered elastic composites, it is shown that negative energy refraction is accompanied by positive phase-velocity refraction and posi…
