Experimental Identification of Viscoelastic Properties of Rubber Blends by Means of a Torsional Rheometer
The dimensioning of injection heads for the extrusion of rubber profiles is exclusively based on empiric knowledge of the non-linear flow behaviour of elastomers. The swelling of the extrudate when emerging from a capillary is typical for viscoelastic fluids, such as polymers and rubber blends, respectively. Therefore, the experimental investigation and numerical treatment of this swelling beha...
متن کاملInfluence of Crystallization and Filler Degree on Viscoelastic Properties of Rubber Compounds
The dimensioning of injection heads for the extrusion of rubber profiles is exclusively based on empiric knowledge of the non-linear flow behavior of elastomers. Thus, the design of injection heads is carried out with subject to the used rubber compound, whereas the geometry of the appropriate profile is achieved by empiric adaptation of the extrusion die. This was one of the motivations for a ...
متن کاملAnalytical Simulations of Optimum Anisotropic Linear Viscoelastic Damping Properties
In a previous paper (Hilton & Yi 1992), a systematic study was undertaken to determine how shapes of relaxation–time functions affect damping characteristics of isotropic viscoelastic materials. The significant parameters were the instantaneous and fully relaxed moduli (Regions A and E on Fig. 1), the two “knees” (B and D), the central slope (C) and anisotropic shift functions. The sensitivity ...

متن کاملViscoelastic properties of bamboo
Dynamic viscoelastic properties of bamboo were determined in torsion and bending. Damping, measured by tan δ, in dry bamboo was relatively small, about 0.01 in bending and 0.02 to 0.03 in torsion, with little dependence on frequency in the audio range. In wet bamboo, damping was somewhat greater: 0.012 to 0.015 in bending and 0.03 to 0.04 in torsion. The anisotropy in damping implies a purely c...
