Dynamical fracture instabilities due to local hyperelasticity at crack tips
Article Abstract:
A generalized model is reported that describes the onset of instability as a competition between different mechanisms controlled by the local stress field and local energy flow near the crack tip, in order to show that hyperelasticity plays a governing role in the onset of the instability. It is seen that such instabilities are intrinsic to dynamical fracture and they help to explain a range of controversial experimental and computational results.

Hyperelasticity governs dynamic fracture at a critical length scale
Article Abstract:
Hyperelasticity play a governing role in the dynamics of fracture and governs the crack speed when the hyperelastic zone approaches the critical energy length scale. The concept of a characteristic length scale for the energy flux near the crack tip is introduced.

Association of the jets of Enceladus with the warmest regions on its south-polar fracture
Article Abstract:
Several studies are conducted to determine the association of the jets of the Enceladus, the satellite of Saturn and the warmest regions on its south-polar fractures. The strongest jets are found in the regions of Baghdad and Damascus.
