A thin-walled 1" square steel tube is crushed in a hydraulic machine. The walls slowly fold over each other as it shortens.

  • is it failing due to its low section capacity?

  • Buckling occurs because the walls are thin. The section is strong but buckling occurs well before any gross seciton yielding.

  • plastic deformation

  • Materials yielding columns not buckling. i didnt see any lateral displacement

    Id like to know the thickness.

  • 4000-8000lbs, it fluctutes between buckling and folding.

  • how much force?
