I am working on rubber bushing, consisting of two metal plates and a sandwiched layer of rubber. I am using ABAQUS to run the FEA models to optimize the bond geometry to reduce the stresses. I have run two cases so far
Design-1: Straight walled rubber
Design-2: Concavity on the wall
In pure...
PJ, Thanks for your feedback. Since i am getting high stresses, it probbaly means the real life application will also see high stresses, but my analysis cannot predict what happens once it gets into the non-lineriaties.
At the material discontinuities, the node values are way higher than those...
I am modelling a elastomer bonded to a metal in ABAQUS. An ideal bond between them (using tie constraints) is assumed. When I ran the analysis, I got high stresses at the interace and upon refining the mesh, the stress values continued to rise. My questions are
1) How believable are the stress...
When modelling corners in FEA, how can you check if the calculated von mises stresses there are accurate? Currently,
1)i look at the strain enrgy error for the entire model, and make sure it is < 10%
2)Check if applied force/moment is equal and opposite to the reaction moment/force
Whats' a...
I am trying to model a cylinder (1mm thick, 16mm dia, 5mm height) of stainless steel. The cylinder has cuts made in its wall with the intention of making it flexible in pure compression. What kind of elements would be good such an analysis?

Ravi
