Hi
all,
I
am an ABAQUS novice working on a graduation project. My model is a
reinforced concrete Tee-joint with steel rebars and stirrups embedded to the
concrete. The concrete is modeled using the Damage-Plasticity model, with
mostly default suggested values. The elastic and plastic values are
derived from experimental values. In addition to the embeddment, the
column and the beam is tied together using the tie command. The model is
subjected to an axial load as well as a displacement force.
The
error that I am getting is :Too many attempts made for this increment after a
runtime of ~ 1 hour, with many warnings similar to this:
-The strain increment is so large that the program will not attempt the
plasticity calculation at 1914 points
-The plasticity/creep/connector friction algorithm did not converge at
23038 points
I
have been stuck for the past week, I do not why this is not working. I
have attached the cae model for your convenience. Any comments and
suggestions are greatly appreciated!
Thank
you!
Ben
