  Hard magnetic materials belong to a novel class of soft active materials with
the capability of quick, large, and complex deformation via applying an
external actuation. They have an extensive range of potential applications in
soft robots, biomedical devices, and stretchable electronics, etc. Recently,
investigation on the experimental and theoretical nonlinear mechanics of hard
magnetic soft cantilevers has received notable considerations. In the available
analyses, the most attention was paid to the non-bifurcation-type nonlinear
mechanics of the system, and bifurcation was considered for a specific case. In
the current study, the general trend of bifurcation-type nonlinear mechanics of
hard magnetic soft cantilevers is introduced and the effective parameters on
the occurrence of bifurcation are identified. Additionally, new trajectories
due to the bifurcation and the corresponding workspace are presented.
Eventually, a comprehensive comparative study between the new trajectories and
workspace with those reported in the prior studies is carried out.
