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

Effect of synthesized zinc stearate on the properties of natural rubber vulcanizates in the absence and presence of some fillers
TL;DR: In this article, zinc stearate was synthesized by precipitation method through two steps; neutralization of stearic acid by sodium hydroxide, then double decomposition using zinc sulphate to precipitate zinc Stearate.

Large Displacement Aspects on Fracture Testing with Double Cantilever Beam Specimens
TL;DR: In this article, the double cantilever beam specimen for fracture testing was investigated for large displacement conditions, and explicit relations for use in experimental situations were derived for two different loadings, transverse force and bending moment.

A review of the determination of energy release rates for strips in tension and bending. Part I – static solutions:
TL;DR: In this paper, it is shown that solutions for the energy release rate G may be obtained for a uniform strip by simply considering the change in length of the strip, which enables a wide range of boundary conditions and material properties to be incorporated into the analysis.

Puncture of elastomer membranes by medical needles. Part II: Mechanics
TL;DR: In this article, a method was developed based on the change in strain energy with the puncture depth to evaluate the fracture energy associated to puncture, and the results showed that the phenomenon of puncture by medical needles involves contributions both from friction and fracture energy, in a similar way as for cutting.

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.
