Topology optimization with linearized buckling criteria in 250 lines of Matlab
Structural And Multidisciplinary Optimization, 2021We present a 250-line Matlab code for topology optimization for linearized buckling criteria. The code is conceived to handle stiffness, volume and buckling load factors (BLFs) either as the objective function or as constraints.

Buckling and free vibrations of CNT-reinforced cross-ply laminated composite plates
Mechanics based design of structures and machines, 2020This article deals with the investigation of free vibration and buckling behaviors of carbon nanotube (CNT)-reinforced cross-ply laminated composite plates. The plate kinematics is assumed to follow a first-order shear deformation theory (FSDT).

To buckle or not to buckle [PDF]
Nature Materials, 2019 Epithelial layers under compression avoid buckling by active contraction, but only up to a well-defined threshold at 35% strain, beyond which buckling occurs.

Buckling loads of nano-beams in stress-driven nonlocal elasticity
Mechanics of Advanced Materials and Structures, 2020Size-dependent buckling of compressed Bernoulli-Euler nano-beams is investigated by stress-driven nonlocal continuum mechanics. The nonlocal elastic strain is obtained by convoluting the stress field with a suitable smoothing kernel.

Buckling and Post-Buckling of a Pumpkin Balloon
51st AIAA/ASME/ASCE/AHS/ASC Structures, Structural Dynamics, and Materials Conference<BR> 18th AIAA/ASME/AHS Adaptive Structures Conference<BR> 12th, 2010Pumpkin shaped balloon has been playing an important role in many space science explorations. This paper presents a computational study of buckling and post-buckling behavior of a 10 m diameter, 145 lobe pumpkin balloon, with lobes of approximately uniform radius. The ABAQUS commercial finite-element package is used.

Buckling and Post-Buckling of Spherical Caps
Journal of the Engineering Mechanics Division, 1971The results of a numerical study of the buckling and initial post-buckling behavior of clamped shallow spherical shells under axisymmetric band type loads are presented. This behavior is studied, first, for a cap with fixed geometry when the radial location of a band load of constant width is allowed to vary; second, for a cap with fixed geometry under

Buckling and post-buckling of graphene tubes
Mechanics of Advanced Materials and Structures, 2015AbstractBuckling and post-buckling of a long, thin, inextensible tube made of graphene material acted upon by a uniform normal pressure are considered. A system of differential equations governing the equilibrium states of such a tube is derived.
