One of the emerging themes of fish-inspired robotics is flexibility. Adding flexibility to the
body, joints, or fins of fish-inspired robots can significantly improve thrust and/or efficiency …

Nearly all fish have flexible bodies that bend as a result of internal muscular forces and
external fluid forces that are dynamically coupled with the mechanical properties of the body …

Designing soft robots poses considerable challenges; automated design approaches may
be particularly appealing in this field, as they promise to optimize complex multimaterial …

Flexibility of marine animal fins has been thought to enhance swimming performance.
However, despite numerous experimental and numerical studies on flap** flexible foils …

Abstract Fluid–structure-interaction (FSI) phenomena with multi-phase flow dynamics and
structural damage commonly exist in engineering practice, which however bring great …

When subjected to a steady cross-flow, the deformation of flexible blades is known to result
in the alleviation of the internal stresses in comparison to rigid structures. In the field of …

Many animals that swim or fly use their body to accelerate the fluid around them, transferring
momentum from their flexible bodies and appendages to the surrounding fluid. The …

Research on fish locomotion has made extensive progress towards a better understanding
of how fish control their flexible body and fin for propulsion and maneuvering. Although the …

In the present experimental study, we investigate thrust production from a pitching flexible
foil in a uniform flow. The flexible foils studied comprise a rigid foil in the front (chord length) …

A robotic fish is used to test the validity of a simplification made in the context of fish
locomotion. With this artificial aquatic swimmer, we verify that the momentum equation …
