Stress analysis software
Stress analysis software
(OP)
I am looking to build an experimental plane from plans, but in the UK the authorities insist on some form of stress analysis. My question is "Is there any reasonably priced (probably only use it once) computer software available to calculate wing spar loads and strength. Similarly the loads and strength required for wing mountings?"

I may be wrong here but they seem to find a previously designed spar that has succesfully carried the same or greater load and used that, working on the theory that it worked before it will work again. Not very efficient but reduces design time and costs greatly.

Since this is a wooden spar, there are some things that Bruhn doesn't cover, but are amply covered by ANC-18. That's available if you know where to look (I found it on the internet).
I'm surprised the UK authorities are insisting on such a step. Then again, they insist on many surprising things...
