Tearing of free-standing graphene [PDF]
Physical review. E, Statistical, nonlinear, and soft matter physics, 2013 We examine the fracture mechanics of tearing graphene. We present a molecular dynamics simulation of the propagation of cracks in clamped, free-standing graphene as a function of the out-of-plane force.

Machine learning control for disruption and tearing mode avoidance
Physics of Plasmas, 2020 Real-time feedback control based on machine learning algorithms (MLA) was successfully developed and tested on DIII-D plasmas to avoid tearing modes and disruptions while maximizing the plasma performance, which is measured by normalized plasma beta. The

Kelvin–Helmholtz versus Tearing Instability: What Drives Turbulence in Stochastic Reconnection? [PDF]
Astrophysical Journal, 2019 Over the last few years it became clear that turbulent magnetic reconnection and magnetized turbulence are inseparable. It was not only shown that reconnection is responsible for violating the frozen-in condition in turbulence, but also that stochastic ...

Calculations in the theory of tearing instability [PDF]
Journal of Physics: Conference Series, 2018 Recent studies have suggested that the tearing instability may play a significant role in magnetic turbulence. In this work we review the theory of the magnetohydrodynamic tearing instability in the general case of an arbitrary tearing parameter, which ...

Proceedings of the National Academy of Sciences of the United States of America, 2018 Significance We show high-resolution P and S images of the subducted Indian mantle lithosphere, which has been torn into four main pieces. The tearing provides a unified mechanism for (i) Late Miocene and Quaternary rifting, (ii) mantle earthquakes in ...

THREE-DIMENSIONAL SIMULATIONS OF TEARING AND INTERMITTENCY IN CORONAL JETS [PDF]
Astrophysical Journal, 2016 Observations of coronal jets increasingly suggest that local fragmentation and intermittency play an important role in the dynamics of these events. In this work, we investigate this fragmentation in high-resolution simulations of jets in the closed ...

Vertical tearing of subducting plates controlled by geometry and rheology of oceanic plates
Nature Communications, 2023 Lateral non-uniform subduction is impacted by continuous plate segmentation owing to vertical tearing of the subducting plate. However, the dynamics and physical controls of vertical tearing remain controversial.

Effect of V and N on the microstructure evolution during continuous casting of steel [PDF]
, 2012 Low Carbon (LC) steel is not expected to be sensitive to hot tearing and/or cracking while microalloyed steels are known for their high cracking sensitivity during continuous casting. Experience of the Direct Sheet Plant caster at Tata Steel in Ijmuiden (

A variational model of fracture for tearing brittle thin sheets [PDF]
, 2018 Tearing of brittle thin elastic sheets, possibly adhered to a substrate, involves a rich interplay between nonlinear elasticity, geometry, adhesion, and fracture mechanics.
