Abstract:
This work demonstrates a repeatable two step-laser cutting and heat-treatment process for manufacturing bistable mechanical structures. This can reliably induce bistability, and through tuning of the laser processing parameters the snap-through force of the structure can be adjusted.
Methods:
The snap-through force of the bistable structure was measured using a Mach-1 MA056 (Biomomentum Inc., Canada) mechanical testing machine equipped with a 10 N load cell. To assess the repeatability of the measurement technique two different single sample repeat tests were performed:
1. Remount repeatability test – A single sample was mounted, tested, removed, re-mounted and re-tested.
2. Lateral force repeatability test – A single sample was mounted, tested, reset and re-tested without removal.
Keywords:
Laser-based manufacturing; Heat-treatment; Bistable structure; Snap-through.
Utilisation des équipements
Le Mach-1 MA056 a mesuré la force latérale nécessaire pour faire basculer des structures en titane traitées au laser entre deux états stables. Une cellule de 10 N servait aux essais de répétabilité. Il s’agit d’un essai de basculement structurel, et non d’un essai de traction du matériau.
