Study on the energy characteristics of rocks under cyclic loading and unloading.
Article in Scientific reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
The deep-buried rock masses influenced by prolonged geological processes have accumulated vast amounts of energy. This stored energy is released due to disturbances in the external environment, a series of geological disasters is triggered. In this study, triaxial cyclic loading tests were carried out on sandstone and granite at different strain amplitudes to investigate the variation of rock internal energy. Stress-strain curves were recorded under various amplitudes. The calculation model of dissipated energy, elastic energy and plastic energy was established. Energy variations are analyzed to explore the dissipation mechanism of internal energy in rocks. The results show that with the increase of strain ratio, the dissipated energy, elastic energy and plastic energy all increase. When the strain ratio reaches a certain range, the slope of energy increase exhibits a sudden change. The study of the rock failure mechanism from the perspective of energy offers practical and guiding significance for the safety assessment and stability prediction of various geological disasters.
