Hi,
Assume there is a small pipe and a large pipe. The small pipe is concentrically inside the large pipe but they are not in contact (i.e. gap between the outside of the small pipe and inside of the large pipe). The analysis goes through multiple steps causing each of these pipes to deform independently. Now in the next step, in reality, a liquid is injected between the pipes to fill the gap between the pipes and impose a pressure to both pipes. The liquid then solidifies (but doesn't 'stick' to either pipe), so, in reality, any load applied from outside on the large pipe will transfer to the inner small pipe due to contact. Is there a way to model this step in Abaqus? In other words, is there a way to numerically fill the gap between the pipes and insert an artificial contact pressure between two parts which are not touching and make the software think that they will be in contact after that point in the analysis?
Thanks,
Sina
