Damage mechanisms in the dynamic fracture of nominally brittle polymers
Davy Dalmas, Claudia Guerra, Julien Scheibert +1
Linear Elastic Fracture Mechanics (LEFM) provides a consistent framework to evaluate quantitatively the energy flux released to the tip of a growing crack. Still, the way in which…
Intermittent stick-slip dynamics during the peeling of an adhesive tape from a roller
Pierre-Philippe Cortet, Marie-Julie Dalbe, Claudia Guerra +4
We study experimentally the fracture dynamics during the peeling at a constant velocity of a roller adhesive tape mounted on a freely rotating pulley. Thanks to a high speed camera…
Understanding fast macroscale fracture from microcrack post mortem patterns
Claudia Guerra, Julien Scheibert, Daniel Bonamy +1
Dynamic crack propagation drives catastrophic solid failures. In many amorphous brittle materials, sufficiently fast crack growth involves small-scale, high-frequency microcracking…
Brittle/quasi-brittle transition in dynamic fracture: An energetic signature
Julien Scheibert, Claudia Guerra, Fabrice Célarié +2
Dynamic fracture experiments were performed in PMMA over a wide range of velocities and reveal that the fracture energy exhibits an abrupt 3-folds increase from its value at crack…
