The addition of wood to polymers results in wood-polymer composites (WPC), whereby the content can be up 80 %. This composite is mainly processed extruded deckings. extrusion die an essential part process, which determines both process parameters and final product. A characteristic WPC dies a partial solidification melt before leaving die. necessary ensure dimensionally stable extrusion. For de...

the liquefaction resistance of soil can be evaluated using laboratory tests such as cyclic simple shear, cyclic triaxial, cyclic torsional shear as well as field methods like standard penetration test (spt), cone penetration test (cpt) and shear wave velocity (vs). in this regard, this study attempts to compare the results of the spt based on the simplified procedure proposed by seed and idriss...

During severe impact conditions, brain tissue experiences a rapid and complex deformation, which can be seen as a mixture of compression, tension and shear. Diffuse axonal injury (DAI) occurs in animals and humans when both the strains and strain rates exceed 10% and 10/s, respectively. Knowing the mechanical properties of brain tissue in shear at these strains and strain rates is thus of parti...

Recent experiments by Holtzman et al. [2003] demonstrate that partially molten aggregates of many mantle materials undergoing simple shear (from ∼ 100−500% strain) will spontaneously develop localized melt-rich bands. These bands develop at small strains but persist at low angles to the plane of shear (∼ 15– 20) even at large shear strains. The melt-rich bands also appear to form localized weak...

Rectangular waveguide is one of the earliest types of transmission lines. Rectangular waveguide can be produced by hot extrusion process. In this paper, the hot extrusion process of CuZn5 rectangular waveguide was investigated by Finite Element Method (FEM). In addition, Genetic Algorithm (GA) was used to optimize the die geometry and process conditions to achieve the lowest magnitude of extrus...

Rheological parameters for ice II Experimental Method and ice III, needed in tectonic models of the icy satellites of the major planets, are obtained from Extrusion experiments were carried out as extrusion experiments and compared with the rheolfollows. Approximately 2 cm $ of distilled water ogy of ice I at pressures ~2 kbar and temperatures was introduced into the 9.5-ram bore of a piston~24...
