Re: [TCML] hoop stress in primary coil
Hi Jim,
A very straightforward analysis of B field and resulting hoop stress
calculation for a simple loop can be found in section 3.3.1 of the
following article from MIT.
http://ocw.mit.edu/NR/rdonlyres/E23FEEB3-AAEC-434E-997B-6950DAD6A121/0/chap3.pdf
The magnetic pressure (P) is proportional to the square of the B field,
and the resulting hoop stress for a "thin" turn is P*(a/t), where a =
radius of coil, and t = thickness of the turn.

Anyone have a cookbook approximation kind of equation for the hoop
stress in the primary? Or even, a single turn coil, given di/dt, etc.
Tnx
