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

Regulating Thermogalvanic Effect and Mechanical Robustness via Redox Ions for Flexible Quasi-Solid-State Thermocells
TL;DR: In this paper , a flexible quasi-solid-state TEC is proposed based on the rational design of a hydrogel electrolyte, of which the thermogalvanic effect and mechanical robustness are simultaneously regulated via the multivalent ions of a redox couple.

A test method to measure fatigue crack growth rate of rubbery materials
TL;DR: In this article, a test method is introduced using a newly designed test machine to characterize the fatigue crack growth behavior under repeated load expressed as a crack growth rate, i.e. crack length per cycle, as a function of the tearing energy, determined by a broad range of the strain energy density in a test piece of pure shear geometry.

A plane stress finite element method for the prediction of rubber fracture
TL;DR: In this paper, a virtual crack extension method using isoparametric finite elements, which are formulated based on a variation of geometry mapping, is used to calculate the tearing energy of rubber vulcanizates.

A Simplified Model to Determine the Contribution of Strain Energy in the Failure Process of Thin Biological Membranes during Cutting
TL;DR: In this article, the authors investigated the resistance to fracture of a thin biological membrane, using the example of animal skin, and calculated the fracture resistance of skin samples from experiments to be 2.32 ± 0.40 kj m-2.

Fracture Mechanics Applied to Rubber Abrasion
TL;DR: In this paper, a fracture mechanics based approach is used to interpret other failure processes in rubbers, which directly relates the abrasion of rubber by a knife edge to its crack-growth characteristics.

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.

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.
