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 ...

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

Helical buckling of thin rods: FE modelling
MATEC Web of Conferences, 2018 In this paper, we utilize the Finite Element (FE) method to model twisting of long thin rods and capture the bifurcation scenarios leading to heli- cal buckling and various further post-buckling states.

Post-Buckling Behaviour of Steel Structures with Different Types of Imperfections
Applied Sciences, 2022 In this paper, the stability of steel members with a complex initial geometrical imperfection pattern are analysed. This issue is extremely important in the case of slender structures, characterised by multiple close critical loads and modal interactions,
