Instability Dynamics of Fracture
|
The fracture of two-dimensional notched solids under tension was
studied using million atom systems. Many recent laboratory findings
occur in the simulation experiments, one of the most intriguing being
the dynamic instability of the crack tip as it approaches a fraction
of the sound speed.
Here are two animations that show visualizations of the large-scale
and atomistic dynamics.  (351 kB) Large-scale
Atomistic (1.6 MB) The visualizations
were created using PV-WAVE.
Here is a hyper-media version of a
paper about this study which was published in Physical Review Letters
(Farid F. Abraham, D. Brodbeck, R.A. Rafey and W.E. Rudge, Phys. Rev.
Lett. 73, 272 (1994)).
Colliding microasperities
 This molecular dynamics simulation was motivated by the head-disk interface.
Here are two animations showing two microasperities colliding at low and high impact velocities.
(209 kB) Low
(214 kB) High
These visualizations were created using Data
Explorer.
