AbstractAbstract
[en] This thesis deals with the short wavelength collective dynamics of dense binary fluid mixtures. The analysis shows that at the level of linearized generalized hydrodynamics, the longitudinal modes of the system separates essentially into two parts - one involves the coupling of partial density fluctuations of the two species and the other involves coupling of longitudinal momentum and temperature fluctuations. The authors have shown that the coupling of longitudinal momentum and temperature fluctuations leads to an adequate description of sound propagation in such systems. In particular, they show that structural disorder controls the trapping of sound waves in dense mixtures. The coupling of the partial density fluctuations of the two species leads to a simple description of the partial dynamic structure factors. The results are in agreement with the molecular dynamics simulations of soft sphere mixtures. The partial density fluctuations are the slowest decaying fluctuations on molecular length scales and it turns out that nonlinear coupling of these slow modes leads to important corrections to the long time behavior of the time correlation functions determining the shear viscosity in dense mixtures

AbstractAbstract
[en] Multilayer glass fiber reinforced polymer (GFRP) laminates filled with nanoclay was manufactured with compression moulding machine. In the present work, five kinds of nanoclay (Cloisite 25A) loadings viz. 2, 4, 6, 8 and 10% on weight basis of epoxy resin were employed to modify the interlaminar shear strength (ILSS), critical energy release rate (GIc) and impact energy properties of GFRP laminates. Experimental results obtained from ILSS test on clay filled GFRP confirm that the superior strength was attained at low clay content of 155.10 MPa. Furthermore, the mode I interlaminar fracture toughness test conducted on DCB specimens revealed that the commanding improvement of GIc was obtained at 2 wt.% clay content level. On the other hand, both ILSS and fracture toughness was getting reduced at higher clay loadings. At last, the impact strength of the test samples was investigated by using Izod impact test apparatus and observed that the impact energy was increased by 44.39% for 2 wt.% and followed by 24.87% for 4 wt.% clay loadings.

AbstractAbstract
[en] Lap splice is considered the best method of jointing reinforcing deformed steel bars (rebars) in reinforced concrete members. Large shear walls are used in nuclear power plants. The purpose is to seize the influencing parameters on the structural characteristics of lap splice in shear wall. Authors have developed a test method by which lap spliced specimens at shear stress zones are subjected to tensile force at both ends. 19 specimens were tested and arranged for testing 7 parameters.

AbstractAbstract
[en] When a (011) plane of a single crystal of molybdenum undergoes a shear stresses in whatever direction Δ, the macroscopic shear takes place along a direction Δ'. It can be considered as the result of two shear deformations along (111) directions. The stresses which are required to produce the shear deformation in the (111) directions depend on the direction of the shear stress and do not obey the law of the critical shear stress
[fr]
Lorsqu'un plan du type (011) d'un monocrystal de molybdene est sollicite par un cisaillement selon une direction Δ quelconque, le glissement macroscopique a lieu selon une direction Δ'. Il est la resultante de deux glissements conjugues selon des directions de type (111). Les contraintes necessaires au glissement de ces directions (111) sont dependantes de la direction de sollicitation et ne satisfont pas a la loi de cision critiqueOriginal Title

AbstractAbstract
[en] In order to study the relationship between shear stress and volume fraction and shear rate of MRFs, four kinds of MRFs with different volume ratios were prepared. The shear stress of MRFs at different shear rates was tested by rheometer. The shear stress expression of MRFs is obtained by fitting and analyzing the experimental data. The experimental results show that under the same volume fraction, the shear stress of MRF increases slowly, and the apparent viscosity decreases exponentially with the increase of shear rate.

AbstractAbstract
[en] A mechanism is proposed for catastrophic shear in niobium crystals; it involves b=1/2a <111> rather than b=a <100> dislocations. Deformation occurs by a form of kinking which begins as diffuse necking followed by localised necking and geometrical softening

AbstractAbstract
[en] The displacive transformation classification proposed at ICOMAT 79 is reviewed in light of recent progress in mechanistic understanding. Issues considered include distinctions between shuffle transformation vs. self-accommodating shear, dilatation vs. shear-dominant transformation, and nucleated vs. continuous transformation. (orig.)

AbstractAbstract
[en] Experimental analyses have been carried out on tuff masonry specimens in order to investigate the structural behaviour of historical buildings in the Naples area (Southern Italy). Spandrels of post-medieval buildings (late XVI to early XX century) have been analysed, with emphasis on morphological characteristics according to chronological indicators. Results of the experimentation on scaled models (1:10) are discussed and the better behaviour of historical masonry typologies on respect to the modern one is highlighted. Comparison with theoretical formulations of ultimate shear resistance are provided too
