Analysis of Energy Evolution Characteristics of Salt Rock Under Different Loading Rates
Frontiers in Earth Science, 2022 The existing uniaxial compression test results of salt rock under different loading rates are used to study its energy evolution characteristics during deformation and failure in this study. First of all, the influence of loading rate on the total energy

Precursory Analysis of Water-Bearing Rock Fracture Based on The Proportion of Dissipated Energy [PDF]
, 2023 In order to better understand the failure process of water-bearing rocks, samples of water-bearing sandstone were tested uniaxially. The failure process and the development of internal cracks were studied through the evolution characteristics of ...

Energy dissipation in turbulent reconnection [PDF]
Physics of Plasmas, 2021 We study the nature of pressure-strain interaction at reconnection sites detected by NASA's Magnetospheric Multiscale Mission. We employ data from a series of previously published case studies, including a large-scale reconnection event at the magnetopause, three small-scale reconnection events at the magnetosheath current sheets, and one example of ...
