Hello,
I'm trying to simulate a forging process with a deformable blank and a rigid die.
Because the complexity of the die's geometry it was modeled as a discrete rigid body, instead analytical surface. Some doubts below:
1. Which type of elements I suppose to use: quadrilateral (R3D4) or triangles (R3D3)? What I should consider making the choice?
2. Rigid elements have a unit or zero thickness? Should I specify another value?
3. How to create a good mesh for rigid bodies and how it can affect the results in terms of the type and number of elements, since no element-level calculations are performed for rigid elements according to Abaqus Manual? The only thing I read is that a poor mesh can cause the “snag effect”, a situation where a node of the deformable body can be trapped on a sharp corner of the rigid body, avoiding its sliding.
Any tips about meshing rigid bodies will be helpful.
Tks.
