SUMMARY The paper presents a new methodology for identifying sub-surface damage in composite components using a combination of Pulse Phase Thermography (PPT) and Thermoelastic Stress Analysis (TSA).

Abstract The present work shows that thermal expansion experiments can be used to measure the γʼ-solvus temperatures of four Ni-base single-crystal superalloys (SX), one with Re and three Re-free variants. In case CMSX-4, experimental results are in good agreement numerical thermodynamic obtained using ThermoCalc. For alloys, calculated close. Transmission electron microscopy chemical compositi...

Beryllium is an ablator material used in inertial-confinement fusion and hypervelocity impact studies. The thermoelastic properties, structural factors, optical properties of beryllium are important these In this paper, the static ion–ion dynamic adiabatic velocity, along Hugoniot were calculated by ab initio simulations. factors show that atoms randomly distributed. extracted dispersion relati...

Abstract The effect of heat treatment on the microstructure, phase composition, mechanical properties, and microhardness shape-memory Сu–14 wt % Al–3 Ni alloy prepared in nanocrystalline state, which results from severe plastic high-pressure torsion (HPT), is studied. Electron microscopy X-ray diffraction analysis are used combination with electrical resistivity measurements order to obtain dat...

Abstract The present research focuses on two-dimensional deformation in a functionally graded thermoelastic micro-elongated medium. It is supposed that the non-homogeneous properties (thermal and mechanical) of FGM are x-direction. normal mode technique used to acquire analytic expression for displacement components, stress, micro-elongation temperature. cause effect relationship non-homogeneit...
