Statistical physics perspective of fracture in brittle and quasi-brittle materials

P Ray - Philosophical Transactions of the Royal Society …, 2019 - royalsocietypublishing.org
We discuss the physics of fracture in terms of the statistical physics associated with the
failure of elastic media under applied stresses in presence of quenched disorder. We show …

[HTML][HTML] Stretchy and disordered: Toward understanding fracture in soft network materials via mesoscopic computer simulations

J Tauber, J Van Der Gucht, S Dussi - The Journal of Chemical Physics, 2022 - pubs.aip.org
Soft network materials exist in numerous forms ranging from polymer networks, such as

Inequality of avalanche sizes in models of fracture

Diksha, S Kundu, BK Chakrabarti, S Biswas - Physical Review E, 2023 - APS
Prediction of an imminent catastrophic event in a driven disordered system is of paramount
importance—from the laboratory scale controlled fracture experiment to the largest scale of …

Rigidity-controlled crossover: From spinodal to critical failure

H Borja da Rocha, L Truskinovsky - Physical review letters, 2020 - APS
Failure in disordered solids is accompanied by intermittent fluctuations extending over a
broad range of scales. The implied scaling has been previously associated with either …

Record statistics of emitted energies—Prediction of an upcoming failure

Prediction of imminent failure using supervised learning in a fiber bundle model

Diksha, S Biswas - Physical Review E, 2022 - APS
Prediction of a breakdown in disordered solids under external loading is a question of
paramount importance. Here we use a fiber bundle model for disordered solids and record …

Athermal fracture of elastic networks: How rigidity challenges the unavoidable size-induced brittleness

S Dussi, J Tauber, J Van Der Gucht - Physical Review Letters, 2020 - APS
By performing extensive simulations with unprecedentedly large system sizes, we unveil
how rigidity influences the fracture of disordered materials. We observe the largest damage …

Scaling laws of failure dynamics on complex networks

Microscopic insights into the failure of elastic double networks

J Tauber, S Dussi, J Van Der Gucht - Physical Review Materials, 2020 - APS
The toughness of a polymer material can increase significantly if two networks are combined
into one material. This toughening effect is a consequence of a transition from a brittle to a …
