Bio-Inspired Micro-Fin-Assisted Multi-Modal Vascular Intervention. [PDF]
Adv Sci (Weinh)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.

Bifurcation-enhanced ultrahigh sensitivity of a buckled cantilever [PDF]
Proceedings of the National Academy of Sciences, 2018 Significance This work brings together the fields of nonlinear dynamics and precision measurement, aiming to develop a highly sensitive nonlinear mechanical force sensor. We use dynamic force spectroscopy of the buckled cantilever tip in an ambient condition, which allows sensitive detection of the noise-induced flipping near the bifurcation ...

Analysis of multiple bifurcation behavior for periodic structures
Archives of Mechanics, 2020 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]
Bulletin of the Polish Academy of Sciences: Technical SciencesThe 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]
Компьютерные исследования и моделирование, 2018 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.

Strength determination for band-loaded thin cylinders [PDF]
, 2018 Cylindrical shells are often subjected to local inward loads normal to the shell that arise over restricted zones. A simple axisymmetric example is that of the ring-loaded cylinder, in which an inward line load around the circumference causes either ...

Wrinkling prediction procedure in thin sheet metal forming processes with adaptive mesh refinement. Part 1: contact free wrinkling [PDF]
, 2001 Buckling of structures with imperfections, quasi-buckling (QB), is studied. At the bifurcation load, these structures show a smooth transition into one of the stable postbuckling equilibrium states, instead of the traditional sudden change in deflection ...
