This paper presents a comprehensive model coupling the effects of hydrostatic stress, surface/interface stress, phase transformation and the structure of electrodes. First, the governing equation of moving phase interface with hydrostatic stress is established. Under the effect of hydrostatic stress, phase transformation process is much faster, which means phase transformation time is overestim...

This paper reveals the interaction between hydrogen and surface stress in austenitic stainless steel by X-ray diffraction stress measurement and thermal desorption analysis before and after being charged with hydrogen. The surface residual stress was varied by surface finishing using several disc polishing agents. The obtained results show that the residual stress near surface had a significant...

Piezoelectric nanobeams having circular, rectangular and hexagonal cross-sections are synthesized and used in various Nano structures; however, piezoelectric nanobeams with hexagonal cross-sections have not been studied in detail. In particular, the physical mechanisms of the surface effect and the role of surface stress, surface elasticity and surface piezoelectricity have not been discussed t...

In this study, a realistic model for dynamic instability of embedded single-walled nanotubes (SWCNTs) conveying pulsating fluid is presented considering the viscoelastic property of the nanotubes using Kelvin–Voigt model. SWCNTs are placed in longitudinal magnetic fields and modeled by sinusoidal shear deformation beam theory (SSDBT) as well as modified couple stress theory. The effect of slip ...

For concrete, the appearance of temperature load due to hydration heat cementitious materials is inevitable and important structural safety dam. This paper investigates effect different surface insulation measures on thermal stress dam concrete by means finite element simulation calculation. The calculation results show that for lowering concrete. When equivalent coefficient transfer was less t...

This study provides, to the best of our knowledge, first detailed analysis how surface oil modifies air–sea interactions in a two-way coupled model, i.e., coupled–ocean–atmosphere–wave–sediment–transport (COAWST) modified account for oil-related changes fluxes. investigates effects on roughness, wind, and near-surface temperature differences, boundary-layer stability those conditions ultimately...

generally, fatigue failure in an element happens at the notch on a surface where the stress level rises because of the stress concentration effect. the present paper investigates the effect of a notch on the fatigue life of the hsla100 (­high strength low alloy) steel which is widely applicable in the marine industry. tensile test was conducted on specimens and mechanical properties were obtain...

Residual stresses and strains in as-cast and annealed aluminum engine blocks were mapped in the main web area above the bearing split using diffraction. Automated coordinate-mapping of the surface and bulk strains was accomplished with X-ray and neutron diffraction, respectively. LabVIEW-based software was developed for improved efficiency, flexibility and quality of data analysis. In the hoop ...
