Elastic energy storage and the efficiency of movement

open access: yesCurrent Biology, 2022
Movement is an integral part of animal biology. It enables organisms to escape from danger, acquire food, and perform courtship displays. Changing the speed or vertical position of a body requires mechanical energy. This energy is typically provided by the biological motor, striated muscle.

Energy distribution in disordered elastic networks [PDF]

open access: yesPhysical Review E, 2010
Disordered networks are found in many natural and artificial materials, from gels or cytoskeletal structures to metallic foams or bones. Here, the energy distribution in this type of networks is modeled, taking into account the orientation of the struts.
