TL;DR: The model of ideal elastomeric gels is based on two assumptions as discussed by the authors, which can be tested experimentally without invoking any specific models of statistical mechanics, and is shown to capture the trend of the data over four orders of magnitude in the osmotic pressure.

TL;DR: In this paper, the authors adopt the model of growth that factors the deformation gradient into a growth tensor and an elastic deformation tensor, and show that the critical conditions for the onset of creases take a remarkably simple form.

TL;DR: Study of fatigue fracture of polyacrylamide hydrogels of various water contents finds the measured thresholds agree well with the predictions of the Lake-Thomas model for hydrogel of high water content, but not in the case of low water content.

TL;DR: In this paper, a three-dimensional nonlinear finite element formulation for dielectric elastomers is presented, where mechanical and electrical governing equations are solved monolithically using an implicit time integrator, where the governing finite element equations are given for both static and dynamic cases.

TL;DR: A facile and versatile approach to fabricating highly stretchable, exceptionally tough and notch-insensitive magnetic hydrogels, Fe(3)O(4)@Fe-alginate/polyacrylamide (PAAm), is developed, by dispersing alginate-coated Fe( 3)O (4) nanoparticles into the interpenetrating polymer networks ofAlginate and PAAm, with hybrid physical and chemical crosslinks.
