Glass-like dynamics of the strain-induced coil/helix transition on a permanent polymer network
O. Ronsin, C. Caroli, T Baumberger
We study the stress response to a step strain of covalently bonded gelatin gels in the temperature range where triple helix reversible crosslink formation is prohibited. We observe…
Two-step build-up of a thermoreversible polymer network: From early local to late collective dynamics
H. Souguir, O. Ronsin, C. Caroli +1
We probe the mechanisms at work in the build-up of thermoreversible gel networks, with the help of hybrid gelatin gels containing a controlled density of irreversible, covalent cro…
Crack front échelon instability in mixed mode fracture of a strongly nonlinear elastic solid
O. Ronsin, C. Caroli, T. Baumberger
Mixed mode (I+III) loading induces segmented crack front échelon structures connected by steps. We study this instability in a highly deformable, strain-hardening material. We find…
A convective instability mechanism for quasistatic crack branching in a hydrogel
T. Baumberger, O. Ronsin
Experiments on quasistatic crack propagation in gelatin hydrogels reveal a new branching instability triggered by wetting the tip opening with a drop of aqueous solvent less viscou…
From thermally activated to viscosity controlled fracture of biopolymer hydrogels
T. Baumberger, O. Ronsin
We report on rate-dependent fracture energy measurements over three decades of steady crack velocities in alginate and gelatin hydrogels. We evidence that, irrespective of gel ther…
Magic angles and cross-hatching instability in hydrogel fracture
Tristan Baumberger, Christiane Caroli, David Martina +1
The full 2D analysis of roughness profiles of fracture surfaces resulting from quasi-static crack propagation in gelatin gels reveals an original behavior characterized by (i) stro…
