Accurate determination of third-order elastic constants (TOECs) is important for quantifying
the nonlinear elastic responses of solid materials. However, conventional experiments are …

Pump-probe experiments investigate the strain sensitivity of crustal elastic properties,
showing nonlinear variations during the strain cycle. In the laboratory, pre-seismic …

Heterogeneous materials such as rocks, concrete, and granular materials exhibit a strong
elastic nonlinearity. The sensitivity of the elastic nonlinearity to the applied stress and pore …

Dynamic acousto-elastic testing, a pump-probe scheme, is employed to investigate the
recovery of consolidated granular media systems from the non-equilibrium steady state …

The present study investigates the frequency-temperature coupling effects on wave
propagation through granite. The pendulum impact test was conducted on the thermally …

In this paper we present experimental investigation of the frequency dependence of
nonlinear elastic (Murnaghan) moduli of polystyrene samples by the ultrasonic method …

Strong ground motion can induce dynamic strains large enough for the Earth's subsurface to
respond nonlinearly and to cause permanent, or plastic, damage. The 2011 M w 9.0 Tohoku …

Variations in elastic wave velocity and amplitude prior to failure have been documented in
laboratory experiments as well as in a limited number of crustal earthquakes. These …

Because measuring the frequency dependence of elastic properties in the laboratory is a
technical challenge, not enough experimental data exist to test the existing theories. We …

We performed measurements of velocity variations for variable coda waves time lapse using
empirical Green's functions reconstructed by autocorrelation of seismic noise recorded …
