Rivets

Question 1

what are the 4 failure modes for a rivet

Answer 1

• rivet shear
• bearing pressure
• plate failure in tension
• plate failure in shear

Question 2

how is edge load transferred

Answer 2

tansferred via shear in rivets

Question 3

what is the result of using more rivets

Answer 3

+ stronger joints

- more holes –> weaken sheet

Question 4

how is spacing calculated to ensure shear strength = shear tension

Answer 4

tensile stress * As = shear stress * 2Ar

• As = reduced cross sectional area = skin thickness*(rivet spacing, b - diameter)
• Ar = pi*diameter^2/4
