The fusion environment is inherently complex, in which an adequate understanding of response from a plasma chamber system requires integrated (and in some areas coupled) analysis across multiple disciplines (neutronics, thermo-fluids, structural mechanics, electromagnetism etc). An integrated simulation predictive capability, which utilizes a computer based single CAD geometric model where a de...

In this Part I, of a two-part paper, we present a detailed continuum-mechanical development of a thermomechanically coupled elasto-viscoplasticity theory to model the strain rate and temperature dependent largedeformation response of amorphous polymeric materials. Such a theory, when further specialized (Part II) should be useful for modeling and simulation of the thermo-mechanical response of ...

About 0.3 g of freeze-dried and powdered sediment sample was decalcified using HCl. Subsequently Total Organic Carbon (TOC) and δ 13 Corg concentrations were measured using a Fisons Instruments CNS NA 1500 analyzer coupled to a Thermo Delta Plus isotope ratio spectrometer. Results were normalized to international standards. Average analytical uncertainty based on duplicate analyses of sediment ...

We report preliminary results on the development of compact (length < 100 microm) fiber-coupled dielectric-loaded plasmonic waveguide components, including Mach-Zehnder interferometers (MZIs), waveguide-ring resonators (WRRs) and directional couplers (DCs), whose operation at telecom wavelengths is controlled via the thermo-optic effect by electrically heating the gold stripes of dielectric-loa...

We design, fabricate and characterize a CMOS-compatible, Mach-Zehnder-coupled, second-order-microring-resonator filter with large Free Spectral Range and demonstrate non-blocking thermo-optical filter reconfiguration. The device consists of 10-μm radius silicon microring resonators, with an FSR equivalent to that of a structure consisting of 5-μm radii microrings. The structure is reconfigurabl...

in saturated soils, heating induces thermal expansion of both grains and the pore fluid. lower thermal expansion coefficient of aggregates results in the increase of pore pressure and reduction of the effective stress besides subsequent volume changes due to the dissipation of pore pressure and heat transfer. dissipation of thermally induced pore pressure with time is a coupled thermo-hydro-mec...

7000 series aluminum alloys are widely used in the automotive industries for structural lightweight components due to their exceptional high strength to weight ratio. however, this class of aluminum alloy is difficult to join by conventional fusion welding techniques so friction stir welding (fsw) widely is used for welding this alloys. the process has been demonstrated to be effective and is c...

the phase transformation phenomenon due to the crystallographic change of shape memory alloys subjected to mechanical or thermal loading is very complicated. regarding the thermo-mechanical coupling effects in shape memory alloys, in case of high  loading rates, heat generation/absorption during the forward/reverse transformation, will lead in temperature-dependent variation and consequently af...

Geologic disposal is a promising solution for safe permanent isolation of accumulated high-level nuclear waste from powerplants. The behavior host rock highly coupled thermally, hydromechanically, and chemically. Numerical simulations such phenomena the extremely long term (>100,000 years) large length scale (>1 km) geologic remain to be computationally challenging. In this study, methodology h...

In this paper, we define a mathematically consistent set of thermo-acoustic equations via asymptotic multiple scale methods in the low-Mach number limit. The final thermoacoustic equations consist of reacting low-Mach number (LMN) equations for hydrodynamic phenomena and acoustic (AC) equations. The two sets of equations are two-way coupled. The coupling terms depend on which multiple scales ar...
