Summary: In this paper, a new magneto-mechanical constitutive model is established based on the macro-thermodynamic relationship, the micro-magnetic domain theory and Jiles-Atherton-Sablic (J-A-S) theory. The new model accurately predicts the magnetostrictive and magnetic behaviors in ferromagnetic materials under elasto-plastic stress and magnetic field, and greatly improves the prediction accuracy of magnetic parameters related to magnetic non-destructive evaluation (MNDE). It can be widely used in the quantitative study of MNDE and in the research and application of the magneto-mechanical behavior and ferromagnetic materials.

Summary: A generalized nonlinear hysteretic thermo-magneto-elastic vector model has been developed using Taylor series expansion of Gibbs free energy density function, demagnetization physics, and Weiss molecular field. The model accounts for nonlinear elastic strains induced by magnetic domain rotation and includes the pinning of magnetic domain walls.

Summary: Enhancement of magneto-mechanical properties in Fe80Al20 alloys by doping Tb has been demonstrated, showing improved magnetostriction and sensitivity. The increased magnetostriction with Tb content is related to the degree of (110) texture. However, higher Tb content may lead to degradation of magneto-mechanical properties.

Summary: This study reviews the characteristics of commonly used constitutive models for partially saturated soils, and compares their ability to predict the hydromechanical response of tailing materials. Modifications are suggested for the models, particularly in relation to a realistic formulation of the water retention curve and its hysteresis, based on comparison with experimental data. The results indicate a potential trade-off between accurately capturing the volumetric responses during drying/wetting cycles and the stiffness and strength characteristics during shearing.

Summary: Three Fe-based ribbon-type samples prepared by a conventional planar flow casting process are studied to investigate the differences in magnetic behaviors between amorphous and partially crystallized surfaces. The study reveals that the magnetic properties of amorphous samples vary with the size of the selected surface area and the types, widths, and movements of magnetic domains, while the crystallized surfaces exhibit more homogeneous magnetic properties with typical one-jump magnetization reversal.

Summary: A nondestructive method for stress characterization in plate-like structures is proposed, utilizing acoustoelastic effects on guided waves to reconstruct a nonuniform multiaxial stress field. The method combines an analytical acoustoelastic model with time-of-flight straight ray tomography for stress field reconstruction, showing that stress components can be accurately reconstructed in some cases but may vary in accuracy depending on spatial variations.

Summary: The analysis of magnetic Barkhausen noise energy hysteresis cycles is a nondestructive testing method that shows promise in evaluating internal mechanical stresses in ferromagnetic structural steels. The study demonstrates that coercivity is the most sensitive indicator of tensile stress. A multiscale model is developed to simulate stress-dependent anhysteretic behavior, which successfully reproduces the entire cycle. 2D simulation predictions indicate that uniaxial tensile stress can be efficiently identified within a specific angle range of the applied magnetic field. This modeling approach allows the determination of the optimal sensor orientation for different materials and stress configurations.

Summary: This work presents a method for identifying multi-axial stresses in steel pipelines using an electromagnetic non-destructive technique. The proposed method evaluates the impedance variation of an eddy current sensor and is suitable for both ferromagnetic and anisotropic materials. It utilizes a finite-element model that incorporates the magneto-elastic behavior of the material and simulates the variation of the eddy current sensor impedance with stress. Experimental correlations are established with samples extracted from orthogonal directions of a pipeline.

Summary: This paper aims to implement controllable deformation of a structure using Shape Memory Alloys (SMA) actuators. A sensorless displacement estimation method is proposed, which measures the variation of electrical resistivity in SMA springs as a feedback signal in closed-loop position control to obtain surface displacement without external displacement sensors. The proposed method is validated by comparing estimated displacement values with those measured by a laser sensor, showing steady-state errors of 1.14% and 0.42% for the estimated displacement and measured displacement, respectively.

Summary: The martensitic transformation is the main feature of shape memory alloys (SMAs). However, their practical implementation in devices is challenging because the functional properties of SMAs evolve during operation due to interactions between the martensite transformation (MT), detwinning, and plasticity. This study investigates the effects of influential mechanisms in a NiTi alloy using electric resistivity measurements. It is found that plastic strains, rather than elastic strains, are a key factor influencing resistivity variations in SMAs. Additionally, assuming linearity between the fraction of stress-induced martensite and strain transformation can lead to unrealistic interpretations of transformation mechanisms in NiTi wires.
