Hi,

A cohesive interaction  in JCFpm is said to be broken in tension resp.
shear when its tensile resp. shear force threshold is reached for the
first time (afterwards, cohesion is lost: there is no more tensile
strength or shear cohesion in these thresholds, see relevant papers
quoted in the doc)

If a particle initially has 8 cohesive interactions, and than 3 of them break in tension during the time interval [0,t], 
state.tensBreak = 3 at time t, and state.tensBreakRel = 3/8 (similar thing for shear variables)

The corresponding code is in JCFpm Law2 source code, you may search for
"tensBreak" in gitHub Yade webpage
