The use of industrial waste and/or by-products as alternative sources of raw materials in
building materials has become standard practice. The result, more sustainable construction …

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

This paper aims to investigate the application of the Nonlinear Coda Wave Interferometry
(NCWI) method in evaluating the nonlinear interface areas in highly heterogeneous …

Non-classical nonlinear elasticity in micro-inhomogeneous materials such as rocks and
cracked or granular materials leads to a number of phenomena ranging from hysteresis and …

Nonlinear acoustics-based nondestructive evaluation (NDE) techniques have shown great
promise for identification of microstructure and microcracking in a wide spectrum of materials …

Consolidated granular materials and materials with damage at the microstructural level
exhibit anomalous elastic behavior even when excited by low-amplitude elastic waves. Their …

In this paper, the spectral element method is used to perform a parametric sensitivity study of
the nonlinear coda wave interferometry (NCWI) method in a homogeneous or …

This paper reports a numerical study of the sensitivity and applicability of the Nonlinear
Coda Wave Interferometry (NCWI) method in a heterogeneous material with a localized …

Dynamic acoustoelastic testing (DAET) is a nonlinear acoustic technique used to
characterize the nonlinear elastic behavior of materials. To enable the in-situ …

There is no nondestructive evaluation method capable of determining stresses in concrete
structural members in situ. Here, we propose and evaluate a torsional-vibration testing …
