“…The methodology is based on the asymptotic expansion homogenization (AEH) method [e.g., Bensoussan et al., 1978;Sanchez-Palencia, 1980, 1983Guedes and Kikuchi, 1990]. The AEH method has a strong mathematical basis and has been extensively validated and successfully used for the analysis of composite materials [e.g., Vel and Goupee, 2010;Cook and Vel, 2012]. In the field of geology, AEH has recently been used to analyze seismic properties in crustal geomaterials [e.g., Naus-Thijssen et al, 2011a, 2011b.…”

Computational analysis of nonlinear creep of polyphase aggregates: Influence of phase morphology

The constitutive laws of polyphase aggregates dominantly depend on the operative deformation mechanisms, phase morphology and modes, and environmental conditions. Each of these factors has the potential to dramatically affect bulk mechanical properties as well as the local stress and strain rate distributions. To focus on the effects of phase morphology, we have developed a rigorous multiscale approach based on asymptotic expansion homogenization. The proposed methodology has two fundamental goals: (1) accurately predict bulk behavior in aggregates by explicitly taking into account phase morphology and (2) calculate detailed distributions of strain rates, stresses, and viscosities in heterogeneous materials. The methodology is able to consider general nonlinear phase constitutive laws that relate strain rates to stresses, temperature, and other factors such as water fugacity and grain size. We demonstrate the approach by analyzing power law creep of computer-generated and natural polyphase systems and benchmarking the results against analytical solutions. As an outcome of this analysis, we find that the approximation of an aggregate as a power law material is reasonable for isotropic, homogeneous phase distributions but breaks down significantly with high degrees of phase organization. We also present distributions in strain rate, stress, and viscosity for different applied loading conditions. Results exhibit areas of high internal stresses and substantial localization. We describe and provide a freely available software package supporting these calculations.

“…This allowed us to predict the behavior of these multilayered rectangular plates under surface loads with defined inclusion direction. Apart from extending the multiscale method proposed by [15] to taking into account the magnetic effect, the present method is based on a more simple procedure (Mori-Tanaka) to describe the behavior of each layer.…”

“…It should be noted that a same analysis has been proposed by [15] to deal with piezoelectric fiber actuators. However, in this multiscale analysis the behavior of each layer was obtained by periodic homogenization, which needs a more inextricable numerical procedure.…”

The aim of this study is to develop a two-scale tool allowing the detailed analysis of the behavior of fiber-reinforced magneto-electro-elastic composite plates. The work is divided into two major sections. The first one deals with the homogenization of the properties of each layer based on the Mori-Tanaka mean field approach where all needed effective coefficients of each layer are determined. In the second one and in order to perform the analysis of the behavior of the obtained magneto-electro-elastic multilayered plate, the Stroh formalism is used. It allows to predict the effective behavior of such plates and the spatial distribution of the local fields along the layers.

This paper presents a novel pattern recognition approach for a non-destructive test based on macro fibre composite transducers applied in pipes. A fault detection and diagnosis (FDD) method is employed to extract relevant information from ultrasound signals by wavelet decomposition technique. Wavelet transform is a powerful tool that reveals particular characteristics as trends or breakdown points. The FDD developed for the case study provides information about the temperatures on the surfaces of the pipe, leading to monitor faults associated to cracks, leaks or corrosion. This issue may not be noticeable when temperatures are not subject to sudden changes, but it can cause structural problems in the medium and long-term. Furthermore, the case study is completed by a statistical method based on the coefficient of determination. The main purpose will be to predict future behaviours in order to set alarms levels as part of a structural health monitoring system.
