Abstract Deformation of filler-reinforced elastomers is accompanied by a complex internal damage due to stress softening (Mullins effect). The crack growth behavior of filler-reinforced elastomers is made significantly complex by the occurrence of a simultaneous directional stress softening. The influences of the directional stress softening on fast crack propagation normal to the pre-stretching direction are revealed by the comparison using three types of specimens: (I) a low-filled elastomer w...

Abstract The Mullins-type damage behaviors in double network hydrogels have attracted a broad research interest in recent years. However, most of current works focus on characterizing and modeling the uniaxial deformation behaviors of these materials. In this work, we combine experimental and theoretical approaches to investigate the anisotropic damage behaviors of double network hydrogels revealed in multi-axial deformation conditions. We demonstrate that an isotropic damage model based on the ...

We characterize the crack-tip strain field in the high-speed (supershear) crack in the elastomers propagating faster than the shear wave speed of sound (Cs). The dependence of steady-state crack ve...

The incorporation of a stiff and brittle phase into a soft and flexible polymer network makes double network hydrogels remarkably tougher than the conventional one. It also induces a stress softening in cyclic loading, which is seemingly identical to that of filled rubbers. Therefore, material models proposed for double network hydrogel are mostly based on continuum damage theories of filled elastomers. However, recent experimental studies clearly distinguish double network hydrogels from filled...

Anisotropy of strain-induced internal damage in tough double network (DN) hydrogels is characterized by a sequence of two tensile experiments. Firstly, the virgin DN gels are subjected to a single biaxial loading–unloading cycle using various combinations of the two maximum strains λx,m and λy,m in the x- and y-directions (λx,m ≥ λy,m). Secondly, the rectangular subsamples, which are cut out from the unloaded specimens so that the long axis can have an angle (θ) relative to the larger pre-strain...
