“…Until recently theoretical and experimental research emphasized the behavior of a single shear band. However, in cases where the loading rate is very high and the specimen is large enough, multiple shear bands have been observed to form in metallic or ceramic specimens (Nesterenko et al, 1998;Nesterenko, 2001;Xue et al, 2002). It has been found that this array exhibits a self-organized pattern, with a characteristic spacing between bands.…”

“…Solitary waves discussed in this study are compact nonlinear stress waves that can travel through uncompressed or weakly compressed chains of particles where adjacent particles are in contact with each other. 1–8 The discreteness and the nonlinear contact between the particles result in unique characteristics. For instance, the solitary waves carry a high level of acoustic energy within a finite width and without distortion.…”

This article presents a method to monitor corrosion remotely, based on highly nonlinear solitary waves, which are compact and nondispersive. In the study presented in this article, two types of solitary wave transducers were used to monitor accelerated localized corrosion on a steel plate. The first type consists of a chain of spherical particles surmounted by a commercial solenoid wired to, and controlled by, a data acquisition system used to lift and release the first particle of the chain and induce the mechanical impacts and stress waves in the chain. The chain included a piezoelectric wafer disk, also wired to the same data acquisition system, to sense, digitize, and store the propagating waves for post-processing. The second type of transducer was identical to the first one but the data acquisition system was replaced by a wireless node that communicated with a mobile device using a Bluetooth connection. Eight transducers were used to monitor the plate for over a week to detect the onset and progression of localized corrosion. Corrosion detection was performed by extracting a few features from the time waveforms and feeding these features to an outlier analysis algorithm based on the Mahalanobis distance. The results of the experiment showed the effectiveness of the proposed monitoring approach at detecting defects close to the transducers and confirm previous numerical predictions by the authors. The experiments also provided evidence that the performance of the wireless transducers is nearly identical to the performance of their wired counterparts, paving the way to a new paradigm for the structural health monitoring of remote structural components in harsh environments.

“…However, the questions of how an ASB formation and develops after instability and how it interacts with the boundaries or neighboring localizations still require further understanding. Nesterenko, Xue et al [11][12][13][14] proposed a controlled way to create multiple shear bands in collapsing thick-walled cylinder (TWC). Another approach of study of ASBs is to model it by numerical simulating via numerical computations and constitutive modeling [15][16][17][18], because a numerical simulation can easily include a Corresponding author: dongxinlong@nbu.edu.cn nonlinear effects or check the limits of a theoretical solution.…”

Abstract. The adiabatic shear bands (ASB) of the tubular metal specimens expanded explosively have been studied by many researchers in the recent years. The onset and evolutions of the multiple shear failure of metal cylinder under explosive loadings are affected by many factors such as the characteristics of the impulsive loadings, the dynamic behavior of the materials, etc. In this work, we investigate the failure and fragmentation of 45# steel cylinder shell driven by the JOB9003 explosive. Experimental and FEM numerical simulation investigations are made for cylinder modeled shell. The results show that for the perfect homogeneous FEM model, the failure mechanism of cylinder shell is differs from that of the experiments, in which the spalling originates is oriented by high intensity of rarefaction wave. Through numerical experiments, it was found that distributed geometrical defects of cylinder shell affect the fragmentation process and mechanism, in which the strain localization controlled by the defects and shear bands initiate on the inter-surface of the cylinder shell.
