Effective speed of sound in phononic crystals
A. A. Kutsenko, A. L. Shuvalov, A. N. Norris
A new formula for the effective quasistatic speed of sound in 2D and 3D periodic materials is reported. The approach uses a monodromy-matrix operator to enable direct integrati…
On the effective shear speed in 2D phononic crystals
A. A. Kutsenko, A. L. Shuvalov, A. N. Norris +1
The quasistatic limit of the antiplane shear-wave speed ('effective speed') in 2D periodic lattices is studied. Two new closed-form estimates of are derived by employing tw…
Spectral properties of a 2D scalar wave equation with 1D-periodic coefficients: application to SH elastic waves
A. A. Kutsenko, A. L. Shuvalov, A. N. Norris +1
The paper provides a rigorous analysis of the dispersion spectrum of SH (shear horizontal) elastic waves in periodically stratified solids. The problem consists of an ordinary diff…
