I am working on crack propagation analysis of lamellar microstructures using XFEM. everything is working fine but i have an annoying observation that whenever i change the damage stabilization parameter let say from 1e-5 to 1e-6 then the force-displacement curves changes abruptly and the force which i am measuring on a reference node of my indenter varies two to three times. i tried to see if damage stabilization parameter effect the F-D curves and i observed that crack length and F-D curve changes.
