Foreshadowing elastic instabilities by negative group velocity in soft composites

Foreshadowing elastic instabilities by negative group velocity in soft composites

We reveal the existence of a state in soft composites, characterized by the omni-directional negative group velocity in the vicinity of elastic instability. We show that the appearance of the negative group velocity in layered and fibrous composites foreshadows microscopic loss of the stability. In...
