In this article, the authors used linear and nonlinear ultrasonic approaches to characterize dolomitic limestone rock using complex moduli, which is estimated using ultrasonic dilatational and Shear phase velocity measurements and corresponding attenuations.Abstract:
Characterization of dolomitic limestone rock is presented using linear and nonlinear ultrasonic approaches. The
linear approach is based upon the concept of complex moduli, which is estimated using ultrasonic dilatational and
shear phase velocity measurements and the corresponding attenuations. The nonlinear approach is based upon noncollinear
wave mixing, involving mixing of two dilatational waves. Criteria were used to assure that the detected
scattered wave originated via wave interaction in the limestone and not from nonlinearities in the testing equipment.
These criteria included frequency and propagating direction of the resultant scattered wave, and the time-of-flight
separation between the two primary waves and the resulting scattered wave. Three cases of non-collinear interaction
of two longitudinal waves are presented and discussed including one that requires only access to a plane surface of
the stone test sample.read more

Characterisation of oxidative ageing in asphalt concrete using a non-collinear ultrasonic wave mixing approach
TL;DR: In this article, a non-collinear wave mixing of two dilatational waves was used to assess the oxidative ageing of asphalt concrete using wave interaction in the concrete and not from nonlinearities in the testing equipment.

Damage characterization in dimension limestone cladding using noncollinear ultrasonic wave mixing
TL;DR: In this article, a method capable of characterizing artificial weathering damage in dimension stone cladding using access to one side only is presented, using a nonlinear approach based upon noncollinear wave mixing, which involves mixing two critically refracted dilatational ultrasonic waves.
Dissertation
Damage evaluation in dimension limestone using nonlinear ultrasonics
TL;DR: A study conducted by Chin et al. as mentioned in this paper found that 40% of failures were due to a reduction in the strength of the stone cladding due their exposure to weather, e.g., temperature variations.

TL;DR: In this article, the elastic behavior of a rock is probed, for instance, it shows extreme nonlinearity hysteresis and discrete memory (the Flintstones could have had a computer that used a sandstone for random access memory).

TL;DR: In this article, a new technique is developed to determine the dispersion relation and the propagational speeds of waves in dispersive solids, which can be applied to measurements of acoustic or electromagnetic wave speeds in other dispersive media.
