Section area of fastener (facade) 2

[Gokhan G]

Hi everyone,
I'm currently attempting to determine the section area of 0.033 in2 for a particular component, but I'm having trouble figuring it out. Please refer to the attached document. As far as I can tell, it involves the area where a fastener makes contact with two different materials. How can I calculate this value? Thank you.

Sorry I don’t understand your question? I see nothing on the attachment which relates to a 0.33 square section, I don’t have any idea what t2/t1 ratio is and the nearest thing I can see to the 0.33 section you state is a fastener section of 0.37.

In the document you attached section area of fastener is computed as the nominal cross-section area:
Π r^2 = 3.1415927 (0.217/2)^2 = 0.03698 in^2 ≅ 0.037 in^2

Thank you all. I really appreciate.
@Desertfox sorry typing error. Value 0.037in2
