摘要: Abstract Folding is a manufacturing method which can create complex 3D geometries from flat materials and be particularly useful in cost-sensitive or planar-limited fabrication applications. This paper introduces compliant mechanisms that employ folding techniques origami to evolve material deployed state. We present origami-inspired sacrificial joints, joints have mobility during assembly of the mechanism but are rigid their final position, regions high low stiffness proper alignment flexures folded mechanisms. To demonstrate we fold steel sheet some well-known
