WebPOSSIBLE FAILURE MODES OF A COMPRESSION MEMBER (axially loaded): LOCAL BUCKLING Failure occurs by buckling or deflection of one or more parts of the member, for example: flange or web of an I-section. No overall deflection is observed in this kind of buckling. SQUASHING Squashing occurs in relatively small length columns. WebJul 13, 2024 · Fro example if you cut the cap and bottom of a can of coke and put it under a micro control press, it will buckle along diamond pattern on its wall, twisting around the vertical axis. In columns it happens because of the elastic behavior of the material leading to bifurcation, be it steel or aluminum, wood, etc.
