On the surface Bloch waves in truncated periodic media: scalar-wave primer
Bojan B. Guzina, Shixu Meng, Prasanna Salasiya +1
Much like their counterparts in homogenous elastic solids, waves in periodic media can be broadly classified into Floquet-Bloch body waves, and evanescent surface waves. Our goal i…
On the constitutive behavior of linear viscoelastic solids under the plane stress condition
Bojan B. Guzina, Marc Bonnet
Motivated by the recent experimental and analytical developments enabling high-fidelity material characterization of (heterogeneous) sheet-like solid specimens, we seek to elucidat…
A simple tool for the optimization of 1D phononic and photonic bandgap filters
Prasanna Salasiya, Bojan B. Guzina
We develop an effective computational tool for simulating the scattering of 1D waves by a composite layer architected in an otherwise homogeneous medium. The layer is designed as t…
Plug-and-play analytical paradigm for the scattering of plane waves by "layer-cake" periodic systems
Prasanna Salasiya, Shixu Meng, Bojan B. Guzina
We investigate the scattering of scalar plane waves in two dimensions by a heterogeneous layer that is periodic in the direction parallel to its boundary. On describing the layer a…
Error-in-constitutive-relation (ECR) framework for the characterization of linear viscoelastic solids
Marc Bonnet, Prasanna Salasiya, Bojan B. Guzina
We develop an error-in-constitutive-relation (ECR) approach toward the full-field characterization of linear viscoelastic solids described within the framework of standard generali…
