Initial Postbuckling With a Unique Buckling Mode

2013
Here, we consider problems that belong to the category of Chap. 18, namely problems with Linear Prebuckling, but take a broader view in that we establish a procedure for investigating the initial behavior after buckling—the Postbuckling Behavior.

Dynamic buckling mode of an elastic bar

Applied Mathematics and Mechanics, 1990
The conception of buckling relative initial imperfection is presented in this paper. According to Boulli-Euler beam equation, the dynamic buckling mode of an elastic bar under the homogeneous boundary conditions can be derived by applying the preferred mode analytical method.

Large twist angle of a novel 3D lattice structure via a tailored buckling mode

Mechanics of Advanced Materials and Structures, 2023
A novel 3D centrosymmetric lattice that exhibits a large twist angle during compression is proposed by tailoring the twist buckling mode of a body-centered cubic lattice and a simple cubic truss to the first. The imperfections of offset and multimaterial

Large-Stroke Constant-Force Mechanisms Utilizing Second Buckling Mode of Flexible Beams: Evaluation Metrics and Design Approach

Journal of Mechanical Design, 2020
Compliant constant-force mechanisms (CCFMs), which provide a near constant-force output over a range of displacement, can benefit many applications. This work proposes a novel large-stroke CCFM (abbreviated as B2CCFM) that utilizes the second buckling ...

Nonsinusoidal Buckling Modes of Sandwich Plates

Journal of the Aeronautical Sciences, 1954
Both wrinkling and "quasi-Euler" buckling modes of sandwich plates have hitherto been taken as sinusoidal. In this report the possibility of nonsinusoidal modes is investigated. The core slab material considered is the special orthotropic one which does not resist deformation in its own plane, but only extension and shear­ ing perpendicular to its ...

Post-Buckling Behavior under Mode Interaction

Journal of the Engineering Mechanics Division, 1979
The post-buckling behavior of continuous elastic systems under interaction of two symmetric stable or unstable modes, is considered. For the cases of two stable (unstable) modes with a negative (positive) interaction coefficient, it is shown that mode interaction increases imperfection sensitivity whenever a 2 times 2 energy matrix of the perfect ...

Higher Mode Buckling of Bimetallic Beam

Journal of the Engineering Mechanics Division, 1971
An analysis is made of the thermal buckling and snap-through action of an initially curved bimetallic beam, supported by two hinges at the extremities. A beam theory solution is obtained for the bimetallic element, which shows that the deflection and snap-through response of the bimetallic beam, to increasing temperature, is considerably different from
