From my one direct experience with this sort of mechanism, (apparently known as a Geneva Drive or Maltese Cross mechanism (https://en.wikipedia.org/wiki/Maltese_Cross_mechanism)) it was fairly sturdy - at least, two other parts built of similar materials failed before it did.
I did find this paper (http://http://noerpamoengkas.files.wordpress.com/2009/01/analysis-and-synthesis-procedures-for-geneva-mechanism-design.pdf) if you want to check the numbers yourself.
There's also this blog post (http://www10.mcadcafe.com/blogs/emerging-technologies/2011/03/11/how-good-is-my-design-checklist-for-successful-designs/), containing what seems to be a simulated stress diagram for same.
It seems to be a pretty popular way to translate continuous rotation into stepped rotation, so I expect the relevant strains are fairly well understood...
