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

Work of fracture of PBT/PC blend: Effect of specimen size, geometry, and rate of testing
TL;DR: In this paper, a linear relationship was obtained between the specific total work of fracture, w f, and the ligament length, L. Extrapolation of this linear relationship to zero ligament lengths gave the specific essential work, w e, which for PBT/PC blend was 35 ± 5 kJ/m 2, almost insensitive to geometry and the dimensions of test specimens as well as testing rate.

A universal method to easily design tough and stretchable hydrogels
TL;DR: In this paper, a universal strategy for easily preparing hydrogels that are tough and stretchable without any special structures or complicated processes is reported, which allows to overcome the limitation of low mechanical performance.

Measurement of Rubber Cutting Resistance in the Absence of Friction
G. J. Lake,O. H. Yeoh +1 more
TL;DR: In this paper, a method for assessing the resistance of rubbers to cutting by sharp objects is described, which involves the application of the cutting implement -a razor blade-to the tip of a crack in a stretched tear test piece.

Characterisation of polyurethane networks based on vegetable derived polyol
TL;DR: In this paper, a polyurethane (PU) network based on vegetable derived polyol has been characterised and compared to a synthetic based network, which showed that vegetable networks showed higher solubles' content.

Hydrogel-based strong and fast actuators by electroosmotic turgor pressure
TL;DR: Jiang et al. as discussed by the authors used turgor pressure and electroosmosis to realize a strong and fast hydrogel-based actuator, which can break a brick and construct underwater structures within a few minutes.

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.
