Buckling: Formula to relate Temperature increase with axial Compression

  1. Nov 24, 2012 #1
    hi, does anyone know how to find how much axial pre-compression is required so that buckling will occur after a temperature rise of 50 C°?

    I know the cross section of the pinned at each end copper strip (4mm x 8mm)
    length= 100mm
    E= 100 GN/m^2
    Coefficient of thermal expansion is 18 x 10^-6

    any ideas??

    Start out by determining the compressional stress required to cause buckling without a temperature rise. The formula is in most strength of materials books.
