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.
