Dear all,

I am currently using LSDYNA to model for the masonry structures. It has several parts (brick elements) so need to define the contact within. I would prefer Tiebreak contact algorithms as I would like to model the failure along the interface of these two parts. Could you tell me the exact input parameters that I should use while defining the tiebreak surface to surface contact. Also, what is the difference between the automatic tiebreak surface to surface and tiebreak surface to surface and which would be better. I have some experience to model the interface strength based on normal and shear interface strength that we can provide in tiebreak surface to surface and the friction coefficient. I could not find the better explanation of the other options like SOFT, PENMAX, do these parameters have effect as well.
