Thermomechanical Properties of Polycrystalline Vanadium in Compression

Current induced polycrystalline-to-crystalline transformation in vanadium dioxide nanowires

Vanadium dioxide (VO2) exhibits a reversible insulator-metal phase transition that is of significant interest in energy-efficient nanoelectronic and nanophotonic devices. In these applications, crystalline materials are usually preferred for their superior electrical transport characteristics as well as spatial homogeneity and low surface roughness over the device area for reduced scattering. H...

Strength of Polycrystalline Ceramics under Shock Compression

Thermomechanical Properties of TiNi Shape Memory Alloy

The thermomechanical properties of shape memory effect and superelasticity due to the martensitic transformation and the R-phase transformation of TiNi shape memory alloy were investigated experimentally. The transformation line, recovery stress and fatigue property due to both transformations were discussed for cyclic deformation. The thermomechanical properties due to the R-phase transformati...

Thermomechanical Properties of Woven Fabric Composites

The in-plane thermo-elastic behaviour of woven fabric reinforced composites is analysed using a combination of published micromechanics and finite element techniques. The repetitive unit of an arbitrary woven fabric composite is divided into elements of which the thermo-elastic properties are determined using micromechanics. The properties of the repetitive unit are obtained using the finite el...

Analysis of the Thermomechanical Behavior of Coarse-grained Polycrystalline Aluminum under Tensile Conditions

The aim of this paper is to present the advantages of using Digital Image Correlation (DIC) and Infrared Thermography (IRT) to investigate the thermomechanical behavior of aluminum at the scale of its microstructure. The study combines these complementary imaging techniques: Electron Backscatter Diffraction (EBSD) to characterise the microstructure of the sample, DIC to obtain strain fields and...
