We study the shear-induced fluidization of amorphous solids subjected to external loading by investigating relaxation dynamics deformed states using computer simulation. A simple shear deformation is employed at constant rate thermal glassy materials. The localization and plastic heterogeneity with strain investigated in terms non-affine displacement field. mean square shows an enhanced mobilit...

Fluidization technology has found widespread applications for a variety of chemical and physical transformations since its introduction in the first half 1900s [...]

Results from chaos and recurrence analyses of pressure signals bubbling fluidized beds are presented in this study. The experiments were performed cylindrical columns having internal diameters 2.5 inches, 4 inches 6 while operating conditions, material properties static bed height held constant. Superficial velocity air at the inlet was varied 2.97 to 5.35 times minimum fluidization each column...

FLUENT and EDEM were applied to simulate liquid–solid coupling in a 3D homogenous fluidization. The dynamics of destabilization the granular material immersed by homogeneous fluidization observed. effect initial packing density stack rate on fluidization’s transient regime, configuration particles fluidized bed variation height analyzed discussed. According results, there was an original observ...

Acoustic Fluidization: I introduced the concept of acoustic fluidization in 1979 to explain the astonishingly low strength and viscosity exhibited by the collapse of impact craters and the formation of central peaks in lunar craters [1]. The name I gave to this process was not well chosen for the geologic community—“vibrational fluidization” might have been more apt--but that name was already i...

A Markovian Petri net is a stochastic discrete event system (DES) frequently used for analysis and performance evaluation purposes. In the past, the fluidification has been proposed in different DES’s as a relaxation technique for avoiding the ”state explosion problem”. Following the same approach, in this paper a hybrid Petri net model is defined as a partial relaxation of an original Markovia...
