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.

Determination of Elastic Parameters of Lipid Membranes with Molecular Dynamics: A Review of Approaches and Theoretical Aspects

open access: yesMembranes, 2022
Lipid membranes are abundant in living organisms, where they constitute a surrounding shell for cells and their organelles. There are many circumstances in which the deformations of lipid membranes are involved in living cells: fusion and fission ...

Influence of Humidity on the Energy of Specific Strain in the Process of Loading Sedimentary Rocks

open access: yesStudia 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.

Energy Propagation in a Cauchy Elastic Material [PDF]

open access: yesQuarterly 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.

Estimating the rockburst hazard of hard rocks based on laboratory test results

open access: yesVestnik 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

Research on effect of CO2 microbubbles on oil film in pores

open access: yesYouqi dizhi yu caishoulu
The oil displacement technology of the water and gas dispersion system is a new enhanced oil recovery technology developed for low-permeability oilfields with low recoveries, which has obviously increased oil production in Changqing Oilfield.

Variation of Elastic Energy Shows Reliable Signal of Upcoming Catastrophic Failure

open access: yesFrontiers in Physics, 2019
We consider the Equal-Load-Sharing Fiber Bundle Model as a model for composite materials under stress and derive elastic energy and damage energy as a function of strain.

Low-energy elastic electron scattering from helium atoms

open access: yes, 2021
We reinvestigate a key process in electron-atom collision physics, the elastic scattering of electrons from helium atoms. Specifically, results from a special-purpose relativistic polarized-orbital method, which is designed to treat elastic scattering ...

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.

Intrinsically Elastic Robots: the Key to Human Like Performance

open access: yes, 2012
Intrinsically elastic robots, which technically implement some key characteristics of the human muskoskeletal system, have become a major research topic in nowadays robotics. These novel devices open up entirely new control approaches.
