On the method of calculation of buckling and post-buckling behavior of laminated shells with small arbitrary imperfections [PDF]
In the present paper the variant of computational methods of stability and initial post-buckling behavior of isotropic shells was generalized with respect to laminated composite shells. Using methods of the asymptotic analysis of the Timoshenko–Mindlin

Bio-Inspired Micro-Fin-Assisted Multi-Modal Vascular Intervention. [PDF]
A magnetic guidewire with a micro‐fin–integrated tip is introduced for multimodal cardiovascular navigation. The micro‐fins exploit fluid drag to augment magnetic torque, enabling bifurcation traversal at 15 mT, tolerating 45° misalignment, bidirectional crawling, and buckle self‐correction.

Nonlinear Instability Behavior and Buckling of Shallow Arches Under Gradient Thermo-Mechanical Loads
This paper investigates the nonlinear behavior and buckling of shallow arches under gradient thermal and mechanical loading. The gradient temperature varies continuously along the thickness of the cross section of the arch but uniformly distributes over ...

Nonlinear buckling analysis of tower crane structure based on movable boundaries
The tower crane is a typical soaring and complex frame structure, and buckling is an important factor affecting its safety and carrying capacity. Considering the special characteristics of the boundary conditions for the boom structure, a numerical ...

Analysis of multiple bifurcation behavior for periodic structures
The classification of simple singularities in the post-buckling analysis of truss structures is well-known for elastic stability. To focus on multiple singularities including a hilltop bifurcation point (h-BP) and its bifurcation paths, we reviewed the ...

Non-bifurcation behavior of laminated composite plates under in-plane compression [PDF]
The paper deals with bifurcation and/or non-bifurcation post-buckling curves of composite plates under biaxial compression. For different lay-up sequences, a coupling, i.e. extension-bending (EB) is considered. The current investigations present distinct

Buckling problems of thin elastic shells [PDF]
The article covers several mathematical problems relating to elastic stability of thin shells in view of inconsistencies that have been recently identified between the experimental data and the predictions based on the shallow- shell theory.
