The rheological behavior of the nanocomposites was determined in dynamic, transient, and steady-shear flow fields in the molten state. The complex viscosity and storage modulus of the nanocomposites increased markedly with CNC content, particularly at low frequencies; the samples were highly shear ...
6) loss modulus 损耗模量 1. It was concluded that the elastic modulus G′, loss modulus G″ and dynamic viscosity η~ of PLA and its copolymers increases with the increasing of the molecular weight. 结果表明,随着分子量的增加,聚乳酸及其共聚物熔体的弹性模量G′、损耗模量G″及动态黏度η*大...

Quantitative features of 3D and 2D SWE were assessed, including elastic modulus standard deviation (ESDE) measured on SWE mode images and ESDU measured on B-mode images, as well as maximum elasticity (Emax). Adding quantitative features to B-mode US improved the diagnostic performance (p <...

They also observed that the elastic response of PLA tensile specimens was approximately isotropic (same Young's modulus). Geng et al. [14] studied 3D printing polyphenylene sulfide and reported anisotropic tensile and bending strengths. We believe that the interlayer shear strength is the minimum ...
With reference to the ply coordinate system RCSply, the engineering constants may include Young's (tensile) moduli E1 and E2, the shear modulus G12, and Poisson's ratios ν21 and ν23. The ply 70 may be isotropic in the 2-3 plane such that the shear modulus G23 may be expressed as...

As the composition effect is mainly reflected by the factor k or the modulus E, it is sensible that chemical composition should play a role in shear banding, at least in the stable shear-banding regime. The insensitiveness of the CSBV to the chemical composition has an important physical ...
Mechanical performance of Kraft fibre reinforced polypropylene composites: Influence of fibre length, fibre beating and hygrothermal ageing This paper describes the influence of fibre length, fibre beating and hygrothermal ageing on tensile strength (TS), Young's modulus (YM), failure strain (F... ...
