Learning Goal:
To determine the effects of certain geometric shapes, namely fillets and circular cutouts, on the stress distributions inside a rigid body and to determine the maximum applicable axial force in the same rigid body while considering these stress concentrations.
The member shown below is made of steel (σallowσallow = 21.0 ksiksi ) that is 2.50 inin thick. The member is subjected to an axial force PP that is applied at both ends. Let rr = 1.25 inin , ww = 5 inin , hh = 2.5 inin , and dd = 1 inin .
Part A - Stress-concentration factor due to a circular cutout
Determine the stress-concentration factor KK due to the 1-in.in.-diameter circular cutout in the member.
