A thin elastic rod embedded in an elastic medium buckles into an exponentially decaying short wavelength profile under compressive loading beyond a critical value. In this study, we report a combined experimental and theoretical investigation of the buckling profile of a thin elastic rod embedded in an elastic gelatin biopolymer network when fracture of the network happens. Prior models have pr...

Abstract This paper investigates the lateral‐torsional buckling of built‐up cold‐formed steel beams featuring two or three component C‐ sigma‐sections arranged to have a closed loop. Several thicknesses each cross‐section with nominal yield stress values 450 MPa and 550 were tested obtain lateral strength data for range slenderness values. Complementary reference tests conducted on same section...

We report the results of a numerical and theoretical study of buckling in elastic columns containing a line of holes. Buckling is a common failure mode of elastic columns under compression, found over scales ranging from metres in buildings and aircraft to tens of nanometers in DNA. This failure usually occurs through lateral buckling, described for slender columns by Euler's theory. When the c...
