When compressed along its longest dimension, a thin structure such as a playing card collapses into a bent shape that accommodates the imposed compression without a significant change of length. This phenomenon of buckling under compression is ubiquitous in structural mechanics: bridges, marine vessels, and aerospace structures all risk failure due to buckling. Buckling is also widespread in nature: microtubules buckle within the cytoplasm and plant stems bend under their own weight.
