[HTML][HTML] Lower-order symmetric mechanism modes and bifurcation behavior of deployable bar structures with cyclic symmetry
Y Chen, J Feng, Q Sun - International Journal of Solids and Structures, 2018 - Elsevier
Kinematic bifurcation is generally unavoidable for deployable structures. Stating at one
critical point along the compatibility path, a deployable structure could exhibit unexpected …
