Size and shape of terrestrial animals
Neelima Sharma, Madhusudhan Venkadesan
Natural selection for terrestrial locomotion has yielded unifying patterns in the body shape of legged animals, often manifesting as scaling laws. One such pattern appears in the f…
Rheological basis of skeletal muscle work loops
Khoi D. Nguyen, Madhusudhan Venkadesan
Skeletal muscle is subjected to simultaneous time-varying neural stimuli and length changes in vivo. Work loops are experimental representations of these in vivo conditions and exh…
How to run on rough terrains
Nihav Dhawale, Shreyas Mandre, Madhusudhan Venkadesan
Stability of running on rough terrain depends on the propagation of perturbations due to the ground. We consider stability within the sagittal plane and model the dynamics of runni…
Transverse contributions to the longitudinal stiffness of the human foot
Ali Yawar, Lucia Korpas, Shreyas Mandre +1
Humans rely on foot stiffness to withstand the propulsive forces of walking and running. Skeletal adaptations that increase foot stiffness include the medial longitudinal arch (MLA…
Stiffness of the human foot and evolution of the transverse arch
Madhusudhan Venkadesan, Marcelo A. Dias, Dhiraj K. Singh +2
Foot stiffness underlies its mechanical function, and is central to the evolution of human bipedal locomotion. The stiff and propulsive human foot has two distinct arches, the long…
Curvature-induced stiffening of a fish fin
Khoi Nguyen, Ning Yu, Mahesh M. Bandi +2
How fish modulate their fin stiffness during locomotive manoeuvres remains unknown. We show that changing the fin's curvature modulates its stiffness. Modelling the fin as bendable…
