Question

Part A - Stress-concentration factor due to a circular cutout

 

Determine the stress-concentration factor KK due to the 15.0-mmmm-diameter circular cutout in the member. USE Figure A FOR SOLVİNG PROBLEM.

K=?

 

Part B - Stress-concentration factor due to the shoulder fillets

 

Determine the stress-concentration factor KK due to the 10.0-mmmm-radius shoulder fillets in the member. USE Figure B FOR SOLVİNG PROBLEM.

K=?

 

Part C - Maximum applicable axial force P

 

Using the information obtained about the stress-concentration factors in the member, determine the maximum applicable axial force PP that can be applied to the member.

Pmax=?

 

Part D - Maximum applicable axial force P without the circular cutout

 

Using the information obtained about the stress-concentration factors in the member, determine the maximum applicable axial force PP that can be applied to the member if the circular cutout is not present.

Pmax=?

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 (oallow = 165 MPa) that is 76.6 mm thick. The member is subjected to an axial force P that is applied at both ends. Let r = 10.0 mm, w = 50.0 mm,
h = 30.0 mm, and d = 15.0 mm.
