...N. V. David; X.-L. Gao; J. Q. Zheng The stress relaxation behavior of a Twaron CT709 ® fabric/natural rubber composite under a uniaxial constant strain is studied using three viscoelasticity models with different levels of complexity and a newly developed para-rheological model. The three...

...Isamu Riku; Koji Mimura; Yoshihiro Tomita In rubber-blended polymer, the onset of cavitation in the particles relaxes the high triaxiality stress state and suppresses the onset of crazing in the polymer. As a result, large plastic deformation is substantially promoted compared with single-phase...

... behavior of rubber under variable amplitude conditions for a series of experiments using multiaxial ring test specimens. Two filled rubber materials were used and compared in this study; natural rubber, which strain crystallizes, and styrene butadiene rubber (SBR), which does not. A pseudoelastic approach...

... nonlinear, and well fitted by the Tait equation, the shear resistance is extremely small. In contrast, polyurea formed by a spray process shows significant compressibility, inelastic volumetric deformation, and significantly enhanced shear resistance. 04 01 2006 22 03 2006 rubber...

...P. A. Kakavas; G. I. Giannopoulos; N. K. Anifantis This paper presents a mixed finite element formulation approximating large deformations observed in the analysis of elastomeric butt-joints. The rubber has been considered as nearly incompressible continuum obeying the Mooney/Rivlin (M/R) strain...

... was a rubber-modified epoxy resin with 12.5 wt% carboxy-terminated butadiene acrylonitrile (CTBN) elastomer. The shapes of the rubber particles dispersed in adhesive layers of damaged and undamaged specimens were observed with an optical microscope. The damage was distributed along the interfaces between...

...W. V. Mars, Principal Research Engineer; A. Fatemi, Professor This work explores the monotonic and cyclic behaviors of filled, natural rubber. Results of stress-strain experiments conducted under stress states of simple, planar, and equibiaxial tension are presented. The ability of hyperelastic...

...J. Le Guen; F. Thouverez; G. Demoulin; L. Jezequel In this article we present a simplified time model of elastic deformation in rubber. The originality of the method is to provide a model with very few degrees of freedom while conserving the frequential, nonlinear and energetic characteristics...
