    Locally resonant metamaterial for the regulation of damage-related nonlinearity based on second harmonic generation

    A nondestructive testing method based on nonlinear vibration is usually implemented by measuring the intensity of the second harmonic signal. However, such intensity is much lower than that of the fundamental ...

    Formation and evolution mechanism of a catastrophic mudflow in a complex disaster-prone environment in a strong earthquake-disturbance region

    Earthquake-triggered mudflows are typical in scale and hazard, and their formation mechanism is extremely complex. In this study, the liquefaction and mobility mechanisms of a catastrophic mudflow, namely, the...
