Asymmetric-bifurcation snapping, all-or-none motion of Venus flytrap [PDF]
Scientific ReportsThe Venus flytrap is a carnivorous plant that catches insects by snapping rapidly and reopening slowly. To understand the mechanism underlying this asymmetrically reversible motion, a three-dimensional laser profiler was used to measure both static ...

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 ...

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 ...
