Hi Anton, it is very common for concrete (ductile fracture). I use
UniaxialStrainer the same as for compression, just setting strainRate>0.
UniaxialStrainer displaces boundary particles, which solves the problem
of gluing particles to supports, since there are no supports.

Tensile tests are much more senitive to strain rate and dynamic effects
in general, be careful with that (I use .1 of the compression rate).

Also, you can pre-determine localization by using dogbone (hyperboloid)
specimen, as in examples/concrete/uniax.py.
