Dual Role for Heterogeneity in Dynamic Fracture
Itamar Kolvin, Mokhtar Adda-Bedia
We approach the problem of heterogeneous dynamic fracture by considering spatiotemporal perturbations to planar crack fronts. Front propagation is governed by local energy balance…
Crack tip kinematics reveal the cohesive zone structure in brittle hydrogel fracture
Chenzhuo Li, Xinyue Wei, Meng Wang +2
When brittle hydrogels fail, several mechanisms conspire to alter the state of stress near the tip of a crack, and it is challenging to identify which mechanism is dominant. In the…
Nonlinear extension of Kolosov-Muskhelishvili stress function formalism
Oran Szachter, Eytan Katzav, Mokhtar Adda-Bedia +1
The method of stress-function in elasticity theory is a powerful analytical tool with applications to a wide range of physical systems, including defective crystals, fluctuating me…
Unstable cracks trigger asymptotic rupture modes in bimaterial friction
H. Shlomai, D. S. Kammer, M. Adda-Bedia +2
The rupture of the interface joining two materials under frictional contact controls their macroscopic sliding. Interface rupture dynamics depend markedly on the mechanical propert…
The mechanical response of a creased sheet
Frederic Lechenault, Benjamin Thiria, Mokhtar Adda-Bedia
We investigate the mechanics of thin sheets decorated by non-interacting creases. The system considered here consists in parallel folds connected by elastic panels. We show that th…
Finite-distance singularities in the tearing of thin sheets
E. Bayart, A. Boudaoud, M. Adda-Bedia
We investigate the interaction between two cracks propagating in a thin sheet. Two different experimental geometries allow us to tear sheets by imposing an out-of-plane shear loadi…
