Abstract: This seminar presents a class of transformable structures built from scissor like units that exhibit a bistable behavior during their deployment and folding due to the intended buckling of some structural elements [1]. The bistability ensures a stable folded and deployed state, this latter not requiring bracing for sustaining their self weight. The question of the potential application of bistable scissor structures in the domain of civil engineering is explored through the computational modeling of their mechanical behavior (employing the finite element method) and the proposition of multi- and single objective optimization problems for their design [2, 3].
