The Schwarz lantern The sleeves of Mona Lisa are wrinkled in the Yoshimura buckling pattern. 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.
The Miura fold is related to the Kresling fold, the Yoshimura fold and the Hexagonal fold, and can be framed as a generalization of these folds. [3] The Miura fold is a form of rigid origami, meaning that the fold can be carried out by a continuous motion in which, at each step, each parallelogram is completely flat.
DRBFM methodology was developed by Tatsuhiko Yoshimura, a Quality Expert and a professor at Japan's Kyushu University. Yoshimura knew that design problems occur when changes are made without the proper level of supporting documentation. Using the philosophy of preventative measures (Mizenboushi), he created his own philosophy of DRBFM. Dr.
Buckling may occur even though the stresses that develop in the structure are well below those needed to cause failure in the material of which the structure is composed. . Further loading may cause significant and somewhat unpredictable deformations, possibly leading to complete loss of the member's load-carrying capac
Using the free body diagram in the right side of figure 3, and making a summation of moments about point x: = + = where w is the lateral deflection. According to Euler–Bernoulli beam theory , the deflection of a beam is related with its bending moment by: M = − E I d 2 w d x 2 . {\displaystyle M=-EI{\frac {d^{2}w}{dx^{2}}}.}

Fumio Yoshimura (吉村 二三夫, Yoshimura Fumio, 1926 – July 23, 2002) was a Japanese and American sculptor. He was known for his wooden replicas of everyday objects such as plants and machines. He was known for his wooden replicas of everyday objects such as plants and machines.
The upper-left one is a simple frame-and-prong design, while the bottom buckle features an integrated chape or cap-end with a center pin attaching the frame. A buckle or clasp is a device used for fastening two loose ends, with one end attached to it and the other held by a catch in a secure but adjustable manner. [1]
