Nonlinear Instability Behavior and Buckling of Shallow Arches Under Gradient Thermo-Mechanical Loads
Frontiers in Materials, 2022 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 ...

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
