Abstract: Elastodynamic Green's function for anisotropic solids is required for wave propagation modeling in composites. Such modeling is needed for the interpretation of experimental results generated by ultrasonic excitation or ...

Abstract: Ductile metallic materials such as aluminum alloy, brass, and steel are widely used in engineering structures. Monitoring elastoplastic deformation in these materials is important for structural health monitoring (SHM) to ...

Abstract: This article reports the observation made during the compressive fracture process of cementitious materials, which has been studied using nonlinear ultrasonic testing (NUT) and acoustic emission (AE) testing techniques. ...

Abstract: A cracked structure made of two different elastic materials having a Griffith crack at the interface is analyzed when it is subjected to pure shear loading and ultrasonic loading. The waves generated by the applied load ...

Abstract: This paper investigates the applicability of the nondestructive testing and evaluation (NDT&amp

Abstract: When stress in concrete exceeds certain threshold value, microcracks are nucleated, these microcracks can propagate and coalesce forming macrocracks, resulting in the gradual decay of the mechanical properties of concrete ...

Abstract: Peri-ultrasound modeling which is based on nonlocal peridynamics is found and proven to be effective for modeling nonlinear waves propagating and interacting with damages in structures. This work presents the peri-ultrasound ...

Abstract: Ultrasonic wave based techniques are widely used for damage detection and for quantitative and qualitative characterization of materials. In this study, ultrasonic waves are used for probing the response of additively ...
