An efficient stiffened compression panel is usually designed so that

  • A.Overall buckling occurs at a much lower load
  • B.Neither mode is considered
  • C.Local and overall buckling occur at similar loads
  • D.Local buckling occurs at a much lower load than overall buckling

Answer: C

Correct answer: Local and overall buckling occur at similar loads

Whichever mode arrives first ends the panel’s useful capacity, so material invested in making the other mode stronger is wasted. The efficient design balances the two, sizing the skin, the stringer pitch and the stringer section so that local and overall buckling arrive together.
