Hello everyone,
I’m currently working on a bearing load analysis for a laminated composite plate consisting of 20 layers. Below is a summary of the setup and the issue I’m facing:
-
I modeled the bearing load by first creating a node at the center of the hole.
-
Then, I connected this center node to the nodes along the semicircular edge of the hole using SPRINGA elements.
-
A total load of 28 kN was applied at this central node to simulate the bearing force.
-
Upon running the simulation, I observed very high deformation and stress values in the results, which do not align with my analytical predictions.
I’m concerned that either the load transfer mechanism using spring elements or the way the model is constrained might be causing unrealistic results.
Could anyone please provide suggestions on:
- Whether this is the correct approach for applying bearing loads in a composite laminate?
- How to better simulate the bearing effect in this context?
- Any typical checks or common mistakes to look out for while using SPRINGA elements in such analysis?
