I intend to carry out simulation of rod pull-out from cement block. The rod embedded 1mm in the concrete block. I followed two threads related to pullout at these links bar pullout analysis; and bar pullout explicit
I have experimental results which I would like to verify from simulation. Although the theory is explained in the above mentioned threads but for confirmation I am writing here as well. The concrete block is fixed and displacement (say 0.5mm/min) is applied at the free end of the rod. We get resultant of force (y-axis in N or cN) and displacement (x-axis in mm) curve. The results although all are for rod pullout but of the following different types;
(1). Initial increase in load until debonding occurs. At the debonding the load drops and from there starts the frictional bond which leads to either (i) rod pulled out completely or (ii) rod being broken at the pullout stage because the rod strength is reached before being pulled out completely.
(2). Rod breaks/ruptures before debonding because the rod ultimate tensile strength is reached.
I would like to perform separate simulations for all of the above mentioned cases. I could enter different values for ultimate tensile strength (apparent strength) of rod (from experimental results) for each of the above mentioned case which I think would help in determining the rupture point for the rod.
I tried running the simulation in static structural but the results are none. I am not getting any force reaction value, must be something I have missed. The explicit dynamics took much long time on my pc so I could not test the results. I will try it again once I could get idea that where am I doing wrong. I am looking forward for guidance.
