Mechanical Properties of Metasandstone under Uniaxial Graded Cyclic Loading and Unloading

open access: yesApplied Sciences, 2022
The acoustic emission and wave velocity characteristics of metasandstone under graded cyclic loading and unloading were revealed by conducting graded cyclic loading and unloading tests. The results show that the acoustic emission signals of metasandstone samples are mainly generated in the loading phase, and almost no acoustic emission activity is ...

Hysteresis Characteristics of Brittle Rock Deformation under Constant Load Cyclic Loading and Unloading

open access: yesTehnicki vjesnik - Technical Gazette, 2020
This paper mainly explores the deformation characteristics of limestone specimens under constant load cyclic loading. For limestone specimens under uniaxial compression, the stress-strain curve can be divided into three stages: compaction stage, elastic stage and sudden failure stage. Under cyclic loading, the hysteresis loop on the stress-strain curve

Cyclic Loading and Unloading of Weakly Consolidated Sandstone with Various Water Contents

open access: yesSustainability, 2023
Weakly cemented rocks have a loose structure, poor mechanical properties, and soften and disintegrate upon contact with water. Mining operations cause damage and ruptures to rocks under cyclic loading and unloading, leading to serious disasters. This study investigated the effects of cyclic loading and unloading on the mechanical properties of weakly ...

Research on rock triaxial cyclic loading and unloading characteristics based on PFC3D

open access: yesMATEC Web of Conferences, 2022
Numerical methods provide a new way for solving complex geotechnical engineering problems. Firstly, we review the emergence and development of numerical methods, and introduce the basic principles of particle flow discrete element and its application in geotechnical engineering. After that, a method of servo combination of cylinder and loading plate is

Mechanical Behavior of Shale Rock under Uniaxial Cyclic Loading and Unloading Condition [PDF]

open access: yesAdvances in Civil Engineering, 2018
In order to investigate the mechanical behavior of shale rock under cyclic loading and unloading condition, two kinds of incremental cyclic loading tests were conducted. Based on the result of the short‐term uniaxial incremental cyclic loading test, the permanent residual strain, modulus, and damage evolution were analyzed firstly.
