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 temperature on the rupture behavior of highly stretchable acrylic elastomer
TL;DR: In this article, an experimental study has been carried out to investigate the effect of temperature on the rupture behavior of acrylic dielectric elastomer, by using VHB 4910 films with and without an initial crack, the fracture energy at different temperature and stretch rate is measured by pure shear test.

TL;DR: In this article, by means of tensile and pure shear testings, the authors characterised the mechanics of a nanoparticle-hydrogel hybrid system that incorporates a hyper-branched polymer (HBP) with abundant hydroxyl end groups into the matrix of the polyacrylic acid (PAA) hydrogel, and found that the third and fourth generations of HBP are more effective than the second one in terms of strengthening and toughening effects.

Energy release rate of a single edge cracked specimen subjected to large deformation
TL;DR: In this article, the authors carried out a series of finite element (FE) simulations to obtain accurate approximations that are valid for all practical crack lengths and strain levels and showed that the small crack approximation of by Rivlin and Thomas in J Polym Sci 10:291-318.1953.

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.
