Description
The Portevin - LeChatelier effect is a signature of
collective behavior in the deformation of metal alloys. I
will describe a set of experiments to elucidate this, and
the modeling we have done to account (almost) quantitatively
for the results. This is put into context: why the PLC is
thought to ensue, and what does that have to do with the
collective
dislocation dynamics.
