TL;DR: In this article, a torsion device was designed and built for testing the shape fixity and shape recovery of shape memory polymers at large deformation and a simple thermal chamber was used to regulate the thermal environment during testing and a CCD camera was used for recording the deformation.

TL;DR: In this paper, a simple representation of a spherical rigid-phase surrounded by rubber gum and embedded in an homogeneous equivalent medium provides access to the effective volume fraction of fillers for a significant range of filler amount, and for materials in the glassy state.

TL;DR: In this paper, carbon-black filled styrene butadiene rubbers (SBRs) were submitted to successive nonproportional loadings in order to define a general criterion for the Mullins softening.

TL;DR: In this paper, the opening and closing of nanocavities in a model soft nanocomposite subjected to cyclic uniaxial tension were directly studied by real-time small-angle X-ray scattering (SAXS).

TL;DR: In this paper, a volume expansion is observed past a critical elongation, which can be interpreted as the onset of cavitation, and the volume returns to its original value and remains constant upon reloading.
