How can we validate the structural integrity of a small lightweight chassis manufactured from 6063-T6 aluminium that has been welded and then heat treated (back to t6 condition)? A simple FEA model has been created but does not consider any thermal analysis and just gives a basic approximation. We are setting up strain gauges and will perform the test today at around 5pm UK time. I am wondering, is it possible that while performing the strain gauging, could we also measure deflection somehow? Even using a string as a baseline then crudely get a deflection measurement etc. Any suggestions?
This is our first time strain gauging so using it as a sole method to validate our FEA will maybe not be wise.
Thanks for all replies!
