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

The finite deformation field surrounding a mode I plane strain crack in a hyperelastic incompressible material under small-scale nonlinearity
TL;DR: In this paper, a finite deformation analysis of a plane strain mode I crack in a hyperelastic incompressible material is presented, and the nonlinear crack tip field is characterized in terms of its region of dominance under the assumptions of small-scale nonlinearity and compared to the theoretical dominant asymptotic solution for this problem.

Mechanical enhancement of hydrophobically associating hydrogels by solvent-regulated phase separation
TL;DR: In this paper, the authors report the simultaneously strengthening, stiffening, and toughening of a conventionally weak gel, hydrophobically associating hydrogel, by a simple regulation of external solvent.

Stress intensity factor and crack opening for a linearly viscoelastic strip with a slowly propagating central crack
TL;DR: In this paper, the authors calculated the stress intensity and the size of the crack opening for a linearly viscoelastic strip with a slowly propagating central crack and the response to a propagating crack is found by superposition.

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.

The free energy of deformation for vulcanized rubber
R. S. Rivlin,D. W. Saunders +1 more
TL;DR: Load-deformation measurements on a number of natural rubber vulcanizates covering a wide range of hardness are reported in this paper, where the mean chain segment lengths obtained from swelling measurements are given.
