ABAQUS/CAE

i need in programming bem with C++

Hello Everyone,

I am trying to do bending simulation for my master thesis. 

I have a simple  square profile beam meshed with shell element.

Beam constrained at the  ends and rigid cylender pressed at middle of beam.

In the test , reaction force dramatically decreased when it reached at peak value(due to buckling , Reaction force&displacement Plotted). However, in my analysis the behaviour of reaction force is not same. It reaches peak point then the reaction force has not changed (same value nearliy peak values).. I used riks method and static stabilized card but i have not had buckling decreases. I also controlled my Boundary condition.  (I used plastic cards and contact card)

I need your advices

Thank you for your time and help,

Best wishes

Hi I am Yishu

I want to ask is the CAE of ABAQUS strong? Can it handle things like someone does by coding the input file?

Thank!

Sincerely yours,

Yishu

ABAQUS is a commercial software, see its homwpage for more info at http://www.simulia.com/index.html
