TL;DR: In this paper, an acoustic emission (AE) is monitored to characterize the seismic behavior of column foundation and an AE moment tensor analysis is applied to analyze the fracture process quantitatively.

TL;DR: In this paper, a micromechanical model based on a probabilistic approach is implemented in the finite element code CASTEM 2000 to develop numerical simulations that efficiently predict the overall damaged behaviour of random oriented fiber composites.

TL;DR: In this article, an acoustic emission (AE) technique was used to locate the positions of fiber breaks and determine the lenght distribution of the fiber fragments resulting when a composite specimen containing a single fiber is loaded to failure.

TL;DR: In this paper, the acoustic emission (AE) was used to validate the identification and location of destructive processes in reinforced concrete structures using the measurements of acoustic emissions generated by those processes.

TL;DR: In this article, the influence of magnetic fields of various strengths on convective cells and on the excitation mechanisms of acoustic oscillations by calculating the spectral properties of the convective motions and oscillations was investigated.
Abstract: We have used 3D, compressible, nonlinear radiative magnetohydrodynamics simulation to study the influence of magnetic fields of various strengths on convective cells and on the excitation mechanisms of acoustic oscillations by calculating the spectral properties of the convective motions and oscillations. The results reveal substantial changes of the granulation structure with increased magnetic field and a frequency-dependent reduction in the oscillation power in a good agreement with solar observations. These simulations suggest that the enhanced high-frequency acoustic emission at the boundaries of active regions (acoustic halo phenomenon) is caused by changes of the spatial-temporal spectrum of turbulent convection in a magnetic field, resulting in turbulent motions of smaller scales and higher frequencies than in quiet-Sun regions.
