SUMMARY
The discussion focuses on calculating the axial pre-compression required for a copper strip to buckle after a temperature increase of 50°C. The strip has a cross-section of 4mm x 8mm, a length of 100mm, an elastic modulus (E) of 100 GN/m², and a coefficient of thermal expansion of 18 x 10^-6. Participants suggest starting with the compressional stress formula from strength of materials literature to determine the necessary pre-compression for buckling to occur under the specified conditions.
