Mode transitions in buckling and post-buckling of stretched-twisted strips
International Journal of Non-Linear Mechanics, 2020 Abstract The complex buckling behavior of one of the simplest structures, an elastic thin strip under combined stretch and twist loading represents a fascinating example for structural stability analysis. For stretched-twisted strips, in contrast to solely stretched strips, not just the computation of the post-buckling process but also the simulation

Evaluation of Aging Effects on Skin Wrinkle by Finite Element Method
Journal of Biomechanical Science and Engineering, 2008 The reason why the wrinkle suddenly becomes prominent at a middle age is addressed from biomechanical standpoint. The multistage buckling theory we have derived concludes that the sudden enlargement of wrinkle comes from a switch of the specific buckling

Approximation of the critical buckling factor for composite panels [PDF]
, 2012 This article is concerned with the approximation of the critical buckling factor for thin composite plates. A new method to improve the approximation of this critical factor is applied based on its behavior with respect to lamination parameters and ...

Buckling modes in pantographic lattices
Comptes Rendus. Mécanique, 2016 We study buckling patterns in pantographic sheets, regarded as two-dimensional continua consisting of lattices of continuously distributed fibers. The fibers are modeled as beams endowed with elastic resistance to stretching, shearing, bending and twist.

Flexural-torsional buckling of FRP thin-walled composite with various sections
Science and Engineering of Composite Materials, 2014 The flexural-torsional buckling of thin-walled pultruded fiber-reinforced plastic (FRP) members composed of unstiffened, stiffened cruciform- and I-shaped sections under uniform compressive loads was investigated using finite element methods (FEM).
