Study on the effect of the lower limit of cyclic stress on the mechanical properties and acoustic emission of sandstone under cyclic loading and unloading

Theoretical and Applied Fracture Mechanics, 2020
This study is aimed at exploring the effect of the lower limit of cyclic stress (LLCS) on the loading and unloading failure process of sandstone. First, cyclic loading and unloading experiments were performed on sandstone samples under different stress ...

Study on damage evolution and constitutive model of sandstone under the coupled effects of wetting-drying cycles and cyclic loading

Engineering Fracture Mechanics, 2021
A constitutive model for damage is proposed to describe the deformation and strength characteristics of sandstone under the coupled effects of wetting-drying cycles and cyclic loading.

Laboratory investigation of the behavior of a geosynthetic encased stone column in sand under cyclic loading

Geotextiles and Geomembranes, 2020
This paper presents the results of a laboratory investigation into the behavior of a geosynthetic encased stone column (GESC) installed in sand under cyclic loading using a reduced-scale model.

Accelerating Cyclic Loading

2018 IEEE 7th World Conference on Photovoltaic Energy Conversion (WCPEC) (A Joint Conference of 45th IEEE PVSC, 28th PVSEC & 34th EU PVSEC), 2018
In this work, we performed four variations of cyclic load testing on four groups of modules using the LoadSpot tool. Each group first underwent 50 thermal cycles (TC50), 10 humidity-freeze cycles (HF10), and a 2400 Pa static load. Then, the baseline group was tested using standard cyclic loading conditions from IEC 62782, another with double the ...

Inhomogeneous mechanical behaviour of concrete subjected to monotonic and cyclic loading

, 2020
The mechanical behaviour of different parts (top, middle and bottom) of concrete exposed to monotonic and cyclic loading is investigated through laboratory testing. Strain evolution and energy dissipation are found inhomogeneous at different parts of the

Finite element analysis of cyclic lateral responses for large diameter monopiles in clays under different loading patterns

Computers and geotechnics, 2021
It is very important to analyze the lateral cyclic response of monopiles for the design of offshore wind turbines (OWTs). A three-dimensional finite element method for lateral cyclic responses of large-diameter monopiles is developed based on a ...

Effects of prior cyclic loading damage on failure characteristics of sandstone under true-triaxial unloading conditions

, 2020
To investigate the effects of prior cyclic loading damage in rocks on subsequent unloading failure characteristics under true-triaxial conditions, a series of complicated unloading tests incorporating the damage-controlled cyclic loading path and stress ...
