Geometric buckling units
WebChange in geometry of structure under compression – that results in its ability to resist loads – called instability. Not true – this termed buckling. Buckling is a phenomenon that can occur for structures under compressive loads. The structure deforms and is in stable equilibrium (as described in point 1 above).
