It's not going to crack under a well-placed chisel, if that's what you
mean.
There are various nuclear reactions that an electron can undergo.
Hitting a positron is the obvious one. Combining with a proton (under
extremely high pressures, see "neutron star") to form a neutron is
another; that's not generally called "annihilation". (I think more
stuff is involved in that one, like a neutrino.) There are probably
other reactions.
In general, any sufficiently messy part of the universe -- that is,
high-energy conditions -- will have virtual particles flying around
reacting with everything. Positron-electron pairs are one example. So
an electron in those conditions will be messed with in short order.
You could call high-energy conditions "mechanical stress". Like, near
a small black hole which is blasting out lots of Hawking radiation.
