In general, double-fastener testing can lead to un certainty in the bearing stress produced at each fastener hole, due to differences in clearances between the pin and hole and following the onset of damage …
WebSol'n: In order to determine the Average Bearing Stress in the bolt, treat the bolt as a Free-Body Diagram. From the FBD, the Average Bearing Stresses on the top and bottom surfaces of the bolt are: s B,top = P/2 ad = 2.5 kN (10 mm)(10 mm) = 25 MPa. Similarly, the Average Bearing Stresses on the middle surface of the bolt is: s B,mid = P http://www.utias.utoronto.ca/wp-content/uploads/2024/07/1-Design-and-Stress-Analysis-for-Aircraft-Structure-Repair-Beyond-Specification.pdf
