Load Deflection Curve
Load Deflection Curve
(OP)
Hello,
I am modelling a concrete column in ABAQUS and I don't understand the load deflection curve that I get.
The curve reaches a maximum load, decreases and increases again. An image of the curve is attached.
Can someone explain this behavior?
Thanks!

RE: Load Deflection Curve
Was NLGEOM activated? Check also plasticity (and maybe damage) parameter, buckling, kind of snap-through effects, hourglassing, ....
RE: Load Deflection Curve
NLGEOM is activated to take second order effect in consideration.
Thank you for your tips about activating enhanced hourglass control an. I got a better curve.
But now I have another problem. The new curve doesn't reach yielding and the maximum load exceed the expected max load!?
