Corner states in a second-order mechanical topological insulator

Topological boundary modes in mechanical systems have recently attracted great attention due to their unique protection features. Here, tunable corner localization of mechanical waves is numerically and experimentally demonstrated in a continuous elastic plate with hexagonally arranged bolts.
