Cascade Crack in Chain of Beads
Meysam Bagheri, Thorsten Pöschel
We consider a homogeneous chain of spheres linked by liquid bridges under tension. The rupture of a single liquid bridge leads to a fragmentation cascade driven by the inverse rela…
Locomotion of a Scallop-Inspired Swimmer in Granular Matter
Hongyi Xiao, Harol Torres, Achim Sack +1
Understanding swimming in soft yielding media is challenging due to their complex deformation response to the swimmer's motion. We experimentally show that a scallop-inspired swimm…
Shape effects in binary mixtures of PA12 powder in additive manufacturing
Sudeshna Roy, Thorsten Pöschel
The quality of the powder spread in additive manufacturing devices depends sensitively on the particles' shapes. Here, we study powder spreading for mixtures of spherical and irreg…
Granular jamming gripper with integrated suction
Angel Santarossa, Olfa D'Angelo, Achim Sack +1
Granular grippers can manipulate a wide variety of objects, but need to be pressed on the object to conform to it. If the object is placed on unstable ground, e.g., on sand or wate…
