In this research, the Stewart-Cazacu micromechanics coupled damage model is extended and validated adding nucleation coalescence models as new mechanisms. The Ti–6Al–4V titanium alloy chosen a suitable hcp ductile material to be modeled using law. characterization of evolution in addressed throughout quasi-static experimental campaign. Damage relies on situ X-ray tomography data scanning electr...

Directionally-solidified (DS) Ni-base superalloys are commonly applied as turbine materials to primarily withstand creep conditions manifested in either marine-, airor landbased gas turbines components. The thrust for increased efficiency of these systems, however, translates into the need for these materials to exhibit considerable strength and temperature resistance. Accurate prediction of cr...

Gravity currents are very common in nature and may appear in rivers, lakes, oceans, and the atmosphere. They are produced by the buoyant forces interacting between fluids of different densities and may introduce sediments and pollutants into water bodies. In this study, the hydrodynamics and propagation of gravity currents are investigated using WISE (Width Integrated Stratified Environments), ...
