Yoshimura buckling

In mechanical engineering, Yoshimura buckling is a triangular mesh buckling pattern found in thin-walled cylinders under compression along the axis of the cylinder,[1][2][3] producing a corrugated shape resembling the Schwarz lantern.

[4] This buckling pattern is named after Yoshimaru Yoshimura (吉村慶丸), the Japanese researcher who provided an explanation for its development in a paper first published in Japan in 1951,[5] and later republished in the United States in 1955.

[6] Unknown to Yoshimura,[7] the same phenomenon had previously been studied by Theodore von Kármán and Qian Xuesen in 1941.

[8] The crease pattern for folding the Schwarz lantern from a flat piece of paper, a tessellation of the plane by isosceles triangles, has also been called the Yoshimura pattern based on the same work by Yoshimura.

[10] Unlike the Miura fold which is rigidly deformable, both the Yoshimura and Kresling patterns require panel deformation to be folded to a compact state.
