Summary: This paper presents an analysis and numerical results for the axisymmetric vibrations of non-uniform two-dimensional functionally graded circular plates subjected to two-directional temperature distribution based on the exact neutral surface and Mindlin plate theory. The mechanical properties of the plate material are temperature-dependent and graded in thickness and radial direction. The thermal boundary conditions are used to obtain a classical solution for the two-directional heat conduction equation. The numerical solution of thermoelastic equilibrium and axisymmetric motion equations is carried out using the generalized differential quadrature method to compute thermally induced displacements and natural frequencies.

Summary: This study investigated the electronic structure, temperature dependent elasticity, and thermodynamical properties of thermoelectric material NiSbS using the quasi-harmonic approximation. The results showed that NiSbS exhibits metallic behavior with a band characteristic similar to that of n-type heavily doped semiconductors. The temperature-dependent elastic constants decrease with increasing temperature and satisfy stability conditions. Thermodynamical calculations suggest that NiSbS has a weak expansion. These findings predict that NiSbS has good mechanical properties for thermoelectric device applications.

Summary: Elastic strips are used as a model to study shape transitions, and different types of transitions are observed depending on the direction of rotation. It is challenging to derive the normal forms for these transitions, but recent work has made progress in obtaining the normal form for algebraic snap-through. In this study, a method is introduced to analyze the dynamic characteristics of elastic strips near transitions and extend the previous asymptotic analysis to exponential snap-through and buckling transitions. The normal forms determined by this analysis dictate all the dynamic characteristics of the elastic strip near a shape transition.

Summary: In this paper, an analytical method is proposed to determine the axial dynamic buckling strength of stiffened panels with simply supported edges and isotropic linear-elastic materials using the large-deflection theory. The buckling behavior of the attached plates and stiffener are separately expressed by various displacement functions, which are expressed by trigonometric and hyperbolic series. The method is validated by comparing its predictions with finite element results for a typical stiffened plate, and the influence of several critical parameters on the dynamic deflection and critical buckling load are studied.

Summary: This article presents a dynamic analysis method considering the correlation between interval parameters in mechanical systems with clearance joints, by embedding the continuous contact force model and modified friction force model into the deterministic dynamic governing equations derived by the Lagrangian method. The convex ellipsoid model is used to characterize the correlation between interval uncertainties, and a Chebyshev-based convex scanning method is developed to obtain the bounds of dynamic response. The clearance effect and correlations between uncertainties on the dynamic behavior are investigated using a robot manipulator with clearance joint as an example. The results show that the dependence between interval uncertainties induces relatively conservative bounds and should be considered carefully in the case of a large clearance size existing in the mechanical system.

Summary: The study found that the residual stresses on the outer surface of the dense yttria-stabilized zirconia (YSZ) layer were compressive, increased with decreasing temperature, and exhibited nonlinear temperature dependence, particularly below 600 degrees C. An elastic model incorporating micromechanics and laminate theory successfully predicted this nonlinearity, considering the order-disorder transition of YSZ around 600 degrees C and the magnetic transition of NiO at the Neel temperature around 265 degrees C. The implications of these findings for the reliability of solid oxide fuel cells are discussed.

Summary: SiC-fiber-reinforced SiC matrix composite cladding for light water reactor fuel elements is commonly used, but its behavior under high-temperature steam conditions is not well understood. This study conducted stress-rupture tests and found that the failure lifetime of SiC composite cladding in steam environments is relatively short, possibly due to the slow crack growth in fibers caused by steam oxidation.

Summary: A study investigated the environmental stability of materials in hybrid energy systems and focused on siliconized silicon carbide (Si-SiC) prepared via additive manufacturing. The results showed that the oxide scales formed on the surface were dense and continuous, but exhibited some cracking due to thermal expansion mismatches. The study discussed the potential effects of silica volatilization induced by water vapor and silica reduction when exposed to hydrogen, and concluded that the oxide scale is expected to provide protection in hybrid power generation systems.

Summary: Elemental powders of Al, Ti, Sc, and Zr are blended and processed via laser powder-bed fusion to create binary and ternary alloys. The microstructural analysis and mechanical testing show that the addition of Ti results in the formation of primary precipitates, while the addition of Sc and Zr leads to the formation of fine grain bands. The Al-0.25Ti-0.25Zr alloy exhibits comparable strain rates to Al-0.5Zr at low stresses, but significantly higher strain rates at higher stresses during compressive creep testing. Finite element modeling suggests that the connectivity of coarse and fine grain regions is a critical factor affecting the creep resistance of the alloys.

Summary: The limited slip systems of magnesium (Mg) and its alloys hinder their wide applications. By conducting tensile straining experiments, researchers discovered a rate-dependent transition in the dislocation mechanisms of Mg alloys. At high strain rates, glissile dislocations dominate, while easy-glide dislocations dominate at low strain rates. Abundant glissile dislocations do not necessarily improve ductility.

Summary: Inverse temperature dependences of the detwinning stress were observed in face-centered cubic deformation twins in Cu-8at.%Al alloy. The detwinning stress increased with temperature when the pi detwinning mode was involved, but decreased when the pi/3 mode was involved. The dual effect of temperature on the detwinning stress was due to the reduction of internal stresses pre-existing within the deformation twins. The complete reduction of internal stresses at about 530 degrees C led to the equivalence of the critical stresses of different detwinning modes and a decrease in the yield stress anisotropy of the twin/matrix structure.

Summary: The elastic-plastic transition in magnesium alloy Mg-4.5Zn exhibits bursts of deformation, which are characterized by sudden changes in grain orientation. These bursts occur in a coordinated manner among nearby grains, with the highest burst rate observed at the onset of full plasticity. The most significant burst events are associated with twinning, supported by the observation of twinned structures using electron microscopy. The bursts are often preceded and followed by a stasis in peak movement, indicating a certain "birth size" for twins upon formation and subsequent growth at a later stage.

Summary: A novel testing system for miniature specimens is designed to characterize the plastic response of materials for which conventional full-size specimens cannot be extracted. The system has an automated operation process, which reduces the damage to specimens caused by manual handling and improves the stability of the test results. The experiments show that the miniature specimens extracted from stainless steel and aluminum have high reproducibility, and the results are consistent with those of conventional-sized specimens. A correction procedure is provided to consider the influence of surface roughness and heat-affected zone caused by wire EDM.
