Elastic energy storage and the efficiency of movement
Current 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.

Influence of Humidity on the Energy of Specific Strain in the Process of Loading Sedimentary Rocks
Studia Geotechnica et Mechanica, 2019 This article presents the results of tests on the energy properties of sedimentary rocks in the Upper Silesian Coal Basin. The rocks were tested both in an air-dry state and in a water saturation state.

Estimating the rockburst hazard of hard rocks based on laboratory test results
Vestnik MGTU, 2019 The relevance of the problem under study is based on the fact that dynamic fractures of mine workings occur in rock masses when developing mineral deposits. Safety assurance of mining depends on the awareness of proneness of various rock types to brittle

Intrinsic foot muscles contribute to elastic energy storage and return in the human foot.
Journal of applied physiology, 2019 The human foot is uniquely stiff to enable forward propulsion, yet also possesses sufficient elasticity to act as an energy store, recycling mechanical energy during locomotion.

Energy Propagation in a Cauchy Elastic Material [PDF]
Quarterly of Applied Mathematics, 1972 It has been shown by Schouten [1] that in an anisotropic homogeneous elastic material subjected to infinitesimal deformations the energy propagation vector is necessarily normal to the slowness surface. It can be readily shown (see, for example, [2]) that the bicharacteristics are also normal to the slowness surface.

Bifurcations in the regularized Ericksen bar model [PDF]
, 2007 We consider the regularized Ericksen model of an elastic bar on an elastic foundation on an interval with Dirichlet boundary conditions as a two-parameter bifurcation problem.

The effect of size-scale on the kinematics of elastic energy release. [PDF]
Soft Matter, 2017 Elastically-driven motion has been used as a strategy to achieve high speeds in small organisms and engineered micro-robotic devices. We examine the size-scaling relations determining the limit of elastic energy release from elastomer bands that ...

Compliant substrates disrupt elastic energy storage in jumping tree frogs.
Integrative and Comparative Biology, 2019 Arboreal frogs navigate complex environments and face diverse mechanical properties within their physical environment. Such frogs may encounter substrates that are damped and absorb energy or are elastic and can store and release energy as the animal ...
