Bifurcation of hemitropic elastic rods under axial thrust
2013
Quarterly of Applied Mathematics
In this work we consider the analysis of unshearable, hemitropic hyperelastic rods under end thrust alone. Roughly speaking, a nominally straight hemitropic rod is rotationally invariant about its centerline but lacks the reflection symmetries characterizing isotropic rods. Consequently a constitutive coupling between extension and twist is natural. We provide a rigorous bifurcation analysis for such structures under "hard" axial loading. First, we show that the initial post-buckling behavior
