What is a simple formula for calculating a shear strength of pin taking into consideration the yield strength of the material?

Is the pin in single shear or double shear?

The formula is the easy part. It's tailoring it for your specific problem that's the tricky part.

You need to give us much more details.

pin diameter is 80mmm

What is the maximum shear the pin can take?

Pretty top website for anything like this.

I'll do it for you.

Let's use the distortion energy theory: Ssy = 0.58Sy

where Sy = 355 MPa

Therefore Ssy = 206 MPa

I'm assuming you're after the shear force, since you have the yield and diameter.

So F= SSy*A

F = 206*5026mm^2 = 1e6 N

Assuming single shear. It'll be double this for double shear.

I did this quickly in my head, you should probably check my working.

That is one big pin though...

I did it the same way and I checked it against shearforces for bolts I found online. It appears to be right.

With pins in shear

You also have to consider the strength of the pinned material in relation to the pin material.

If the pin is a safety or protection failure device you may need yet further considerations.
