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

A model of the mechanics of shear-crack propagation in tearing for amorphous metals I. Critical shear stress for inhomogeneous flow
H. Kimura,T. Masumoto +1 more
TL;DR: In this paper, a model of the mechanics of shear-crack propagation in tearing is proposed, from which the critical shear stress (τ) of inhomogeneous flow of an amorphous metal can be determined.

Steady-state crack growth in polymer gels: A linear poroelastic analysis
TL;DR: In this article, a semi-infinite crack in a long strip specimen subject to plane-strain loading is studied in detail, and the crack-tip fields from the numerical analysis agree with the asymptotic analysis with a poroelastic stress intensity factor.

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.
