# gst: cascade crack in chain of beads.

›
<< ️(AA) consider a homogeneous chain of spheres linked by liquid bridges under tension. The rupture of a single liquid bridge leads t...

# gst: dual role for heterogeneity in dynamic fracture.

›
<< ️(AA) approach the problem of heterogeneous dynamic fracture by considering spatiotemporal perturbations to planar cra...

# gst: apropos of monopoles with internal degrees of freedom

›
AA << ️ consider a class of spontaneously broken  SU(2)  gauge theories with adjoint scalar and look for exact magnetic monopole solut...

# gst: early warning skill, extrapolation and tipping for accelerating cascades; if the upstream system crosses a tipping point, this can shorten the timescale of valid extrapolation.

›
AA << investigate how nonlinear behaviour (both of forcing in time and of the system itself) can affect the skill of early warning sig...

# gst: defect-free and defective adaptations of crystalline sheets to stretching deformation.

›
<< The elastic response of the crystalline sheet to the stretching deformation in the form of wrinkles has been extensively investigat...

# gst: dynamics of fluid-driven fractures across material heterogeneities.

›
<< Fracture propagation is highly sensitive to the conditions at the crack tip. In heterogeneous materials, microscale obs...

# gst: monitoring of stable crack growth; crack tip behavior at the nanoscale (during ceramic fracture).

›
<< To understand fracture and make brittle materials more ductile, (AA) rely on modeling what happens at a crack tip. How...

# gst: elastomers fail from the edge.

›
<< The performance of soft devices is limited by the fracture resistance of elastomers. (..) A key observation is that thi...

# gst: compression and fracture of ordered and disordered droplet rafts

›
AA << simulate a two-dimensional array of droplets being compressed between two walls. The droplets are adhesive due to an attractive ...

# gst: when science meets poetry, an image of three-dimensional stepped cracks (bistability, and their transition to simple cracks)

›
<< Slow cracks may be simple, with no internal structure. The leading edge of a simple crack, the crack front, forms a sin...
