Are the stresses around local features real or imagined?
Video : 60 minutes presentation and curated Q and A
In some circumstances, the stress levels that we predict from FEA are not physically meaningful.
The stress distribution and high levels of stress locally can be described as an FEA ‘artifact.’
The most common examples where this can happen are:
- Applying a point load
- Creating abrupt local transitions in local loading
- Constraining a model at a point
- Creating abrupt transitions in local constraints
- Abrupt transition between materials
- Sharp re-entrant corners
In this webinar, I’m going to focus on some examples from the list.
I review the background to the accuracy objective. Do the local stresses really matter, from a physical and compliance point of view?
