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

Finite element calculation of energy release rate for 2-D rubbery material problems with non-conservative crack surface tractions
J. H. Chang,Eric B. Becker +1 more
TL;DR: In this paper, the energy release rate for 2D rubbery material problems with non-conservative crack surface tractions is calculated by a modified version of virtual crack extension method with finite element solutions.

Fracture of model end-linked networks

TL;DR: In this paper , a theory of network fracture that accounts for loop defects is developed by drawing on recent advances in network elasticity and is tested against both molecular dynamics simulations and experimental fracture measurements on model gels, and good agreement between theory, which does not use an enhancement factor, and measurement is observed.

Time dependent fracture of polymers
TL;DR: In this paper, the fracture behavior of polymers is reviewed with emphasis on the time dependent aspects of the problem, and the effects of temperature and solvent environment are examined besides the special effects arising from fatigue loading.
Journal ArticleDOI
Polyacrylamide hydrogels. III. Lap shear and peel
TL;DR: In this paper, the authors compare lap shear and peel as tests for measuring toughness and find that the average values of toughness determined by lap shears and peel are comparable, but the plateau force in peel scatters narrowly.

Mixed-mode (I/II) failure assessment of rubber materials using the effective stretch criterion
TL;DR: In this article, the authors extended the effective stretch (ES) criterion from pure mode-I to the general in-plane mixed-mode (I/II) loading in cracked rubber specimens.

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.
