Indentability of Conventional and Negative Poisson's Ratio Foams
Roderic S. Lakes,K. Elms +1 more
TL;DR: In this article, the authors studied the indentation resistance of foams, both of conventional structure and of a novel reentrant structure giving rise to negative Poisson's ratio, using holo graphic interferometry.

Improving mouth guards
TL;DR: A mouth guard with a stiffer insert, which softens at a higher temperature in the occlusal portion, is proposed as a more protective mouth guard.

Anisotropic viscoelastic finite element analysis of mechanically and hygrothermally loaded composites
Harry H. Hilton,Sung Yi +1 more
TL;DR: In this article, quasi-static linear anisotropic viscoelastic responses of composite structures subjected to mechanical and hygrothermal loads are formulated in terms of finite element algorithms.

Impact properties of shear thickening fluid impregnated foams
M. Soutrenon,Véronique Michaud +1 more
TL;DR: In this paper, a soft foam scaffold was impregnated with STF to provide a three-dimensional shape to the assembly at rest, while a silicone was cast around it to serve as a physical barrier to the external environment.

Footwear affects the behavior of low back muscles when jogging.
TL;DR: One of the benefits of running shoes and insoles is improved temporal synchronization between potentially destabilizing external forces and stabilizing internal forces around the lumbar spine.

Viscoelastic properties of polymers
TL;DR: In this article, the authors describe the nature of Viscoelastic behavior of polymeric systems and approximate relations among the linear Viscoels and approximate interrelations among the Viscelastic Functions.

Skeletal transients on heel strike in normal walking with different footwear.
TL;DR: Simultaneous measurements during normal walking of the transient acceleration on heel strike in the tibia and skull show peaks of ∼ 5 g and 0.5 g respectively when hard heels were worn, which indicates Aggravation of symptoms in sufferers from back troubles may well be due to shear induced by them in para-osteal tissue.

An in vivo study of low back pain and shock absorption in the human locomotor system.
Arkady Voloshin,J. Wosk +1 more
TL;DR: The present investigation support the idea that the repetitive loading resulting from gait generates intermittent waves that propagate through the entire human musculoskeletal system from the heel up to the head, and that the human locomotor system tries to prevent overloading of the head from insufficiently attenuated shock waves.

The Hertz problem for a rigid spherical indenter and a viscoelastic half-space
TL;DR: In this paper, the authors investigated the penetration of a viscoelastic half-space by a rigid spherical indenter in a quasi-static approximation, and the analysis was used to estimate the duration of contact and coefficient of restitution for the Hertzian impact of a spherical impact on a Maxwell solid.
