چکیده
In this paper we apply the methodology based on analysis of changes in acoustic wave velocities under static stress for measurements third-order elastic moduli three polystyrene-based nanocomposites with different fillers: SiO2 particles, halloysite natural tubules, and carbon black particles. The samples were fabricated by same technology our data provide information relative nonlinear properties composites caused addition fillers. obtained are compared that commercial grade polystyrene. substantial variations types fillers demonstrated analyzed. results a qualitative agreement theoretical predictions.

Canonical elastic moduli
Every linear planar anisotropic elastic material is equivalent, under a linear change of coordinates, to an orthotropic material. Consequently, up to linear changes of variables, there are just two "canonical" planar elastic moduli which determine the properties of any linearly elastic material. Extensions to three-dimensional elasticity and applications are indicated.
متن کاملMelt-Processable Syndiotactic Polystyrene/Montmorillonite Nanocomposites
Monoalkyland dialkyl-imidazolium surfactants were used to prepare organically modified montmorillonites with markedly improved thermal stability in comparison with their alkyl-ammonium equivalents (the decomposition temperatures increased by ca. 100 °C). Such an increase in the thermal stability affords the opportunity to form syndiotactic polystyrene (s-PS)/imidazolium-montmorillonite nanocomp...
متن کاملElastic Moduli of Precompressed Pyrophyllite
Chao and Ruoff [*] have shown previously that by precompressing pyrophyllite prior to its use in high-pressure applications, one obtains a material which has a uniform density and uniform mechanical properties. We have recently studied the propagation of u trasonir nplIse~ in pyrnphyllit.p specimens to investigate the effect of specimen precompression on the.measured elastic moduli. Measurement...
متن کاملNonlinear Bending Analysis of Sector Graphene Sheet Embedded in Elastic Matrix Based on Nonlocal Continuum Mechanics
The nonlinear bending behavior of sector graphene sheets is studied subjected to uniform transverse loads resting on a Winkler-Pasternak elastic foundation using the nonlocal elasticity theory. Considering the nonlocal differential constitutive relations of Eringen theory based on first order shear deformation theory and using the von-Karman strain field, the equilibrium partial differential eq...
متن کاملeffects of different types of clays and maleic anhydride modified polystyrene on polystyrene/clay nanocomposites
polymer/clay nanocomposites are considered as a new subject of research in iran and the world. addition of a minimum amount of clay (2-5wt%) can improve the mechanical properties, enhance barrier properties and reduce flammability dramatically. polystyrene (ps) exhibits high strength, high modulus and excellent dimensional stability, but it has poor ductility, elongation, and flexural modulus. ...
