A new criterion of coal burst proneness based on the residual elastic energy index
International Journal of Mining Science and Technology, 2021 To evaluate the coal burst proneness more precisely, a new energy criterion namely the residual elastic energy index was proposed. This study begins by performing the single-cyclic loading-unloading uniaxial compression tests with five pre-peak unloading

Minimizing Configurations for Elastic Surface Energies with Elastic Boundaries [PDF]
Journal of Nonlinear Science, 2021 We study critical surfaces for a surface energy which contains the squared $L^2$ norm of the difference of the mean curvature $H$ and the spontaneous curvature $c_o$, coupled to the elastic energy of the boundary curve. We investigate the existence of equilibria with $H\equiv -c_o$. When $c_o \ge 0$ we characterize those cases where the infimum of this

Expression for the granular elastic energy [PDF]
Physical Review E, 2012 Granular Solid Hydrodynamics (GSH) is a broad-ranged continual mechanical description of granular media capable of accounting for static stress distributions, yield phenomena, propagation and damping of elastic waves, the critical state, shear band, and fast dense flow.

The Anticipation of Gravity in Human Ballistic Movement
Frontiers in Physiology, 2021 Stretch-shortening type actions are characterized by lengthening of the pre-activated muscle-tendon unit (MTU) in the eccentric phase immediately followed by muscle shortening.

ON THE REPRESENTATION OF ENERGY AND MOMENTUM IN ELASTICITY [PDF]
Mathematical Models and Methods in Applied Sciences, 2000 In order to clarify common assumptions on the form of energy and momentum in elasticity, a generalized conservation format is proposed for finite elasticity, in which total energy and momentum are not specified a priori. Velocity, stress, and total energy are assumed to depend constitutively on deformation gradient and momentum in a manner restricted ...

Membrane-mediated interactions between disk-like inclusions adsorbed on vesicles
Frontiers in Physics, 2022 Self-assembly of membrane inclusions plays a key role in biological processes such as cellular signalling and trafficking and has potential applications for designing interfacial devices such as sensors and actuators.

Elastic Energy Driven Polymerization [PDF]
Biophysical Journal, 2009 We present a molecular system where polymerization is controlled externally by tuning the elastic energy of the monomers. The elastic energy, provided by a DNA molecular spring, destabilizes the monomer state through a process analogous to domain swapping. This energy can be large (of approximately 10 kT) and thus drive polymerization at relatively low

Achilles Tendon Mechanical Behavior and Ankle Joint Function at the Walk-to-Run Transition
Biology, 2022 Walking at speeds higher than transition speed is associated with a decrease in the plantar-flexor muscle fibres’ ability to produce force and, potentially, to an impaired behaviour of the muscle–tendon unit (MTU) elastic components.
