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

Velocity mode transition of dynamic crack propagation in hyperviscoelastic materials: A continuum model study
Atsushi Kubo,Yoshitaka Umeno +1 more
TL;DR: In this paper, the authors investigated dynamic crack propagation on an elastomer using the finite element method (FEM) with a hyperviscoelastic material model and found that the mode transition phenomenon occurs due to a characteristic non-monotonic temporal development of principal stress near the crack tip.

Lifetime prediction of simple shear loaded filled elastomers based on the probability distribution of particles
TL;DR: In this article, an end-of-life prediction method for filled elastomers has been introduced and applied on fatigue under uniaxial deformations in [1], where measured inhomogeneity size frequencies are assumed to be equal to the sizes of the initial cracks responsible for the final end-life of the elastomer.

A rate-dependent cohesive continuum model for the study of crack dynamics
TL;DR: In this paper, a rate-dependent cohesive continuum model is developed to represent material particles interacting in a viscous medium, where the interactions between material particles are modeled using a cohesive force law while microstructural resistance to relaxation is represented by a phenomenological continuum viscosity function.

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.
