XFEM crack under compression.
Hi all,
I am doing crack modelling (XFEM) under moving compression and traction loading in Abaqus but I get warning regarding the crack under compression load as follows:
"THE LOADING CONDITION MIGHT MAKE MAIN CRACK UNDER COMPRESSION AT NSET "X" THE CRACK PROPAGATION DIRECTION CANNOT BE PREDICTED. A VALUE OF ZERO IS PROVIDED FOR IT."
Anyone facing the same issue?
Kind regards,
Omid

Probably because compression
Probably because compression load in ABAQUS will not affect the damage variable used in Traction-Separation Law, which is adopted in XFEM for damage initiation.
