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

Fatigue crack growth of double-networked natural rubber
Shinyoung Kaang,Chang-Woon Nah +1 more
TL;DR: In this article, double-networked natural rubbers were compared with those of a conventional network (single network) and showed a significant improvement in tensile modulus, tensile strength at break, and strain energy density.

Cracking and Crazing in Polymeric Glasses
TL;DR: Fracture mechanics as discussed by the authors is a theory of the fracture of solids viewed as continuous media, which can be applied to glassy polymers as well as any other class of coherent solids.

Dependence on mean stress and stress amplitude of fatigue life of EPDM elastomers
TL;DR: In this paper, the dependence on test parameters of the fatigue resistance of EPDM was investigated using dumbbell specimens under load control at 1 Hz until failure, and the results of these tests confirmed the well known amplitude dependence of fatigue life in filled rubbers.

Constitutive modeling and the trousers test for fracture of rubber-like materials
TL;DR: In this article, the authors focus on a particular fracture test where two legs of a cut specimen are pulled horizontally apart and show that the cut position plays a key role in the fracture analysis, and that the effect of the position depends crucially on the constitutive model employed.

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.
