On extracting momentum from supports: the bullet in the beam problem
Xiaoyu Zheng, Tianyi Guo, Peter Palffy-Muhoray
To gain insights into momentum transfer from the supporting environment, we consider the simple problem of a bullet, fired from below, into a wooden beam resting on two supports. T…

The effects of network architecture on the photomechanical performance of azo-acrylate liquid crystal elastomers
Anastasiia Svanidze, Sudarshan Kundu, Olena Iadlovska +3
Azo-containing liquid crystal elatomers are photomechanical materials which can be actuated by illumination. The photomechanical response is a result of the photoisomerization of t…
