Steady-State Cracks in Viscoelastic Lattice Models II [PDF]
Physical Review E, 1998 We present the analytic solution of the Mode III steady-state crack in a square lattice with piecewise linear springs and Kelvin viscosity. We show how the results simplify in the limit of large width. We relate our results to a model where the continuum

Effect of crack propagation on crack tip fields [PDF]
Fracture and Structural Integrity, 2013 Crack closure influences fatigue crack growth rate and must be included in the design of components. Plasticity induced crack closure is intimately linked with the crack tip plastic deformation, which becomes residual as the crack propagates.

Fatigue crack propagation analysis considering the dynamic crack-load coupling effect [PDF]
Scientific ReportsGear fillet crack is one of the most common defects of the gear transmission system, and the study of gear fillet crack propagation and life prediction has attracted much attention in the literature. The existence of the crack will alter the dynamic load

Non steady-state intersonic cracks in elastomer membranes under large static strain [PDF]
Journal of Theoretical, Computational and Applied Mechanics, 2021 Dynamic crack propagation in elastomer membranes is investigated; the focus is laid on cracks reaching the speed of shear waves in the material. The specific experimental setup developed to measure crack speed is presented in details.

Steady-state cracks in viscoelastic lattice models [PDF]
Physical Review E, 1999 We study the steady-state motion of mode III cracks propagating on a lattice exhibiting viscoelastic dynamics. The introduction of a Kelvin viscosity $ $ allows for a direct comparison between lattice results and continuum treatments. Utilizing both numerical and analytical (Wiener-Hopf) techniques, we explore this comparison as a function of the ...

Advances in Mathematical Physics, 2022 Compression is a typical stress condition for cracks in deep-water structures, where the cracks tend to close from a nonclosed state, due to a certain gap that exists between the surfaces on both sides of cracks.

2022 IEEE 35th Computer Security Foundations Symposium (CSF), 2022 Bana and Comon have proposed a logical approach to proving protocols in the computational model, which they call the Computationally Complete Symbolic Attacker (CCSA). The proof assistant Squirrel implements a verification technique that elaborates on this approach, building on a meta-logic over the CCSA base logic.

Fatigue crack growth in notched specimens: a numerical analysis
Fracture and Structural Integrity, 2019 Fatigue crack growth (FCG) is linked to irreversible and non-linear processes happening at the crack tip, which explains different problems observed in the use of da/dN-?K curves. The replacement of ?K by non-linear crack tip parameters, namely the crack
