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

Soft prosthesis materials based on powdered elastomers.
S. Parker,Michael Braden +1 more
TL;DR: A new class of soft prosthesis material has been developed, based on the combination of a powdered elastomer and a methacrylate monomer that polymerizes to an elastomers, which may be useful in external prostheses.

Exactly solvable model for a velocity jump observed in crack propagation in viscoelastic solids.
Naoyuki Sakumichi,Ko Okumura +1 more
TL;DR: In this article, an exact solvable model that exhibits the velocity jump incorporating linear viscoelasticity with a cutoff length for a continuum description was proposed, which revealed the physical origin of the speedup.

A new generalized fracture criterion of elastomers under quasi-static plane stress loadings
TL;DR: In this article, Hamdi et al. proposed a fracture criterion of rubber-like materials under plane stress loading, based on the reference axis change principle, which can be applied to the case of solid propellant materials.

Finite strain fracture analysis using the extended finite element method with new set of enrichment functions
Reza Rashetnia,Soheil Mohammadi +1 more
TL;DR: In this article, the authors studied finite strain fracture problems based on appropriate enrichment functions within the extended finite element method and demonstrated that the logarithmic set of enrichment functions provided the most accurate and efficient solution for finite strain fractures.

A convective instability mechanism for quasistatic crack branching in a hydrogel
TL;DR: A minimal, predictive model is built that combines mechanical characteristics of this mesoscopic region and physical features of the process zone and lends support to the idea that non-linear elasticity plays a critical role in crack front instabilities.

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.
