Helicoil shear out area...
Helicoil shear out area...
(OP)
In calculating the shear strength of an helicoil, what is the appropriate shear area:
- the projected area (pi*D*L) or
-just the circumferential area (pi*r*r)?
Note: r & D both are pitch radius and diameter
L = engagement length
- the projected area (pi*D*L) or
-just the circumferential area (pi*r*r)?
Note: r & D both are pitch radius and diameter
L = engagement length





RE: Helicoil shear out area...
Have a look in the helicoil catalogue on page 11:-

But as a rough idea of a shear area for a helicoil, I would use the shear area of the tapped hole your making for the insertion of that helicoil.
