Summary: This paper presents an analytical and explicit theoretical model for the nonlinear magnetoelectric effect in laminated composites, taking into account the multi-field coupled properties of magnetostrictive materials. Analytical solutions of nonlinear ME voltages in various modes are obtained, predicting that the frequency-multiplying behavior observed in the composites can be tuned by bias magnetic field. The optimal bias field for maximum linear voltage and zero nonlinear voltage is obtained.

Summary: This article presents a reliability analysis of a 4-wire grid-tied inverter under different loading conditions, considering unbalanced loads and harmonic distortion in the current consumed. The study found that the presence of harmonic content in the load current, especially low-frequency harmonics like the third harmonic, plays a dominant role in the semiconductors' expected lifetime. Additionally, the phase delay of the harmonic current content and the existence of unbalanced loads were identified as critical factors in the semiconductor's reliability.

Summary: Due to the widespread use of electronic devices, there is a growing demand for energy harvesting technologies. In this study, a generator based on the magnetoelectric effect is proposed as a promising solution. Polymer-based magnetoelectric laminates consisting of piezoelectric and magnetostrictive phases are used to convert magnetic fields into electric voltage. By adjusting the surface morphology of the magnetostrictive substrate, an optimal magnetoelectric coefficient is achieved in binderless laminates. The different magnetoelectric voltage tendencies in the binderless laminates demonstrate the importance of suitable interface configuration for energy harvesting devices.

Summary: Manufacturing uncertainties in composites, such as carbon fiber deviations and voids, can impact mechanical properties. Although experiments have been conducted, quantitative characterization of fiber radius and shape deviations, and matrix void content, remain a challenge. A computational micromechanics study was conducted to understand the effects of manufacturing uncertainties on the mechanical behavior of UD composites under different loading conditions. The methodology involved establishing constitutive laws for constituents, modeling RVEs with deviations based on observations, and predicting stress-strain curves and failure modes.

Summary: The critical condition for the onset of surface instability during the photopolymerization process and the factors affecting wrinkling initiation in photopolymerizing condition were investigated experimentally and theoretically. It was found that the critical time and critical wavelength for wrinkling initiation can be predicted by the developed model. The curing conditions, including irradiation intensity and photoinitiator concentration, significantly influenced the critical time, while the mechanical properties of the material mainly affected the critical wavelength. The findings provide guiding principles for controlling surface morphology in photopolymerization-based designing and manufacturing.
