Hi,

I'm modelling a bar in concrete with applyed force on the bar. When I model them seperately, I get response which is OK, that is - when the steel bar is modeled alone the output spectar (frequency-amplitude) looks OK, and when I model only concrete block its response is also OK. However, when I try to model them together nad apply force on bar, the response I get is the one which corresponds to bar. It doesn't 'recognize' concrete. If I use any contac (no separation, bonded, etc.) i always have the same resonse - response of bar to applyed force. Does anybody have experience with modelling of contact?

Best regards!
