TLDR
The resistance to tearing of a rubber vulcanizate is usually determined by loading in a specified manner a test-piece of the vulcanizer of standard shape, in which a notch has been produced, either in the molding process or by cutting the testpiece in a standard fashion.Abstract:
The resistance to tearing of a rubber vulcanizate is usually determined by loading in a specified manner a test-piece of the vulcanizate of standard shape, in which a notch has been produced, either in the molding process or by cutting the test-piece in a standard fashion. A wide variety of shapes of test-piece and notch and of methods of loading have been recommended by various authors (see, for example, Buist1).read more

On the account of a cohesive interface for modeling the behavior until break of highly filled elastomers
TL;DR: In this paper, a composite model, represented by a 2D periodic cell with randomly dispersed particles, with an account of a cohesive zone at the filler/matrix interface is used.

Stresses at a Crack in an Elastomer
TL;DR: In this article, a microscopical, photoelastic technique has been used to investigate the distributions of stress and strain around a crack in a highly elastic material, natural rubber, and the decay of strain energy in a direction perpendicular to the crack axis is much more gradual when the strains are finite, but the rate of decay along the axis in the elastomer is similar to that predicted by infinitesimal-strain theory.

Electrically-Induced Actuation of Acrylic-Based Dielectric Elastomers in Excess of 500% Strain.
TL;DR: A soft electromechanically-active polymer capable of an electrically-induced linear strain beyond 500% that is continuously tunable by voltage that is simple and highly amenable to integration in robotic systems is demonstrated.

Plane stress finite element prediction of mixed-mode rubber fracture and experimental verification
TL;DR: In this article, a plane stress finite element method was used to predict critical loads of arbitrarily shaped cracked rubber specimens of the mixed-mode type (mode I and II) using a plane-stress finite element (PSFEM) method and utilizing material constants that characterize the mechanical and fracture properties of SBR (Styrene Butadiene Rubber) material determined from experimental tests on a mode I specimen.

Peridynamic correspondence model for finite elastic deformation and rupture in Neo-Hookean materials
TL;DR: In this article, the weak form of peridynamic equilibrium equation is derived based on the Neo-Hookean material model with slight compressibility, and the nonlocal deformation gradient tensor is computed in a bond-associated domain of interaction using the PD differential operator.

Large elastic deformations of isotropic materials IV. further developments of the general theory
TL;DR: In this article, the surface forces necessary to produce simple shear in a cuboid of either compressible or incompressible material and those required to generate simple torsion in a right-circular cylinder of incompressibly material are derived.

Large Elastic Deformations of Isotropic Materials. VII. Experiments on the Deformation of Rubber
R. S. Rivlin,D. W. Saunders +1 more
TL;DR: In this paper, it was shown that the load-deformation curves obtained for certain simple types of deformation of vulcanized rubber test-pieces in terms of a single stored energy function can be interpreted on the basis of the theory of large elastic deformations of incompressible isotropic materials.

An analysis of the conditions for rupture due to griffith cracks
TL;DR: In this paper, the authors present a model in which the crack is bounded by the atoms centred on the planes z =±½a, these planes being the boundaries of two semi-infinite elastic solids.
