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

•Cyclic loading and unloading tests of sandstone with different lower limit of cyclic stress are carried out.•The effects of different lower limit of cyclic stress on the mechanical properties and AE spectrum of samples are compared.•The damage accumulation and deformation characteristics of the sam...
