Hi All,
I am trying to model a simply supported reinforced concrete beam with longitudinal reinforcement. I am using 8-node solid elements for the concrete, and 2-node truss elements for the reinforcement bars. I have embedded the reinforcement bars in the concrete using an Embedded Region constraint. I am then applying a displacement at the midspan (deflection control). I am using the Concrete Damaged Plasticity model for the concrete. My model begins to run, and then is unable to converge once the maximum tensile stress in the concrete reaches the tensile strength of the concrete (concrete cracks). At this point it cannot converge and the model never completes. I am unsure why it is stopping at the concrete tensile strength when I am using reinforcement as well.
Does anyone have any thoughts of what I am missing?
Thanks in advance.
