We simulate the fracture processes of ferroelectric polycrystals in
three dimensions using a phase-field model. In this model, the grain
boundaries, cracks and ferroelectric domain walls are represented in a
diffuse way by three phase-fields. We thereby avoid the difficulty of
tracking the interfaces in three dimensions. The resulting model can
capture complex interactions between the crack and the polycrystalline
and ferroelectric domain microstructures. The simulation results show
the effect of the microstructures on the fracture response of the
material. Crack deflection, crack bridging, crack branching and
ferroelastic domain switching are observed to act as the main fracture
toughening mechanisms in ferroelectric polycrystals. Our fully 3-D
The velocity and instability of crack motion in 2D hexagonal lattice of graphene under pure opening loads
are investigated by atomistic molecular dynamics simulations. The brittle crack along zigzag direction
in a strip can propagate supersonically at even 8.82 km/s under uniform normal loading of edge
displacements. Crack moving straightly at low speeds produces atomically smooth edges, while kinking
occur beyond a critical speed around 8.20 km/s equivalent to 65% of Rayleigh-wave speed in graphene,
Dear all,
I was curious whether there are any
experimental information and / or results regarding the out of plane (anti-plane)
deformation of (very) thin films. For example an elastic thin film subjected to anti-plane loading on its surface. Any other suggestions regarding possible applications of anti-plane loading conditions in thin films would be appreciated.
Thanks a lot,

Dear blog-readers,
As you may know, our research group has, with my leaving the UK, moved in part to Luxembourg, where I am now based. I am of course keeping close ties with Cardiff, where Pierre Kerfriden is now taking care of the group.
It has been a fun and productive year, and I thank you all for contributing to this through numerous discussions emanating from this blog. I wish you all the best for 2014, and hope that it will bring you joy in the work you do.
Best regards from Lausanne where we are enjoying a few days off.
