Abaqus: Abaqus: Antisymmetric stresses in fiber reinforced open hole plate?

Abaqus: Abaqus: Antisymmetric stresses in fiber reinforced open hole plate?

Hello, i am kind of new to abaqus and i am trying to simulate an open hole plate reifnorced with carbon fibres. The fibres should be aligned around the hole based on previously calculated load paths. The example shows two fibre splines around the hole, which are implemented as beam elements and constrained as embedded elements in the matrix. The plate is put under uniaxial tension.
According to the symmety the stress distribution in the upper and lower spline should be the same. I tried different boundary conditions and different mesh styles and sizes. Furthermore the coordinates of the splines are completely symmetric and placed in the center of the plate.
So i am wondering about the cause of this antisymmetry...

Thanks for your help!

First of all take a look at the displacement plot and deformed shape. Check if it's also asymmetric. Then make sure that everything (shape, material, beam profile, mesh, BCs) is the same for both fibre splines.

eBook - Rethink Your PLM
A lot has changed since the 90s. You don't surf the Web using dial-up anymore, so why are you still using a legacy PLM solution that's blocking your ability to innovate? To develop and launch products today, you need a flexible, cloud-based PLM, not a solution that's stuck in the past. Download Now
White Paper - Using Virtualization for IVI and AUTOSAR Consolidation on an ECU
Current approaches used to tackle the complexities of a vehicle’s electrical and electronics (E/E) architecture are both cost prohibitive and lacking in performance. Utilizing virtualization in automotive software architecture provides a better approach. This can be achieved by encapsulating different heterogeneous automotive platforms inside virtual machines running on the same hardware. Download Now
