Luc Scholtès proposed the following answer:
To see cracks in Paraview, you just have to open the crack.vtu files
created during your simulation (to get these, you need to add the
'cracks' attribute in the recorders list and also you have to define the
same "Key" attribute as in the Law functor). Each point you'll see in
the main window corresponds to a crack created during the simulation and
you will be able to see their different attributes (type, onJnt, time of
occurence, etc...).

Two ways to deal with these attributes:
- choosing the attribute in the "coloring" menu
- using the "threshold" function and selecting the attribute you want to threshold (e.g., selecting "onJnt" in  the scalars menu and playing with the min/max values: if min=max=1, you'll see the cracks from joint interactions only, if min=max=0, you'll see the cracks from matrix interactions only). 
By combining these two options, you should be able to distinguish tensile/shear/joint/matrix as you mentioned.

You can also apply glyphs to the cracks files so as to, e.g., associate
a disk to each point (disks are good as they can be oriented according
to the actual crack plane, i.e., the normal plane to the contact). I
opened a thread in the Paraview mailing list when I was trying to do
that: https://www.mail-archive.com/paraview@xxxxxxxxxxxx/msg08166.html
