Hi all,
I've been trying to learn Abaqus and model a slow speed scratching process which replicates an experiment to analyse residual stress.
So far I've been able to model the indentation step but cannot seem to drag the tool across the surface to create the scratch.
I'm not 100% sure I am using the right solver (maybe explicit) or mesh (maybe ALE?), i.e.
*************************************
Model basics and error messages:
- 2D section and analytical rigid body conical tool.
- tip radius 50micron
- cone angle 90 deg.
- RHA elastic - plastic material properties.
- Node to surface interaction discretization.
- Structured quad mesh
- Error / Warning Messages
- Element are distorrting excessively, convergence is unlikely (but it working in the indentation step)
- Sereve contact overclosure exist, convergence is unlikely.
- Excessive distortion at 20 integration points.
- strain increment has exceeded fifty times yield.
