Acoustic Emission Characteristics of Normal and Layered Concrete Blocks during Dilating/Static Fracture

Figure 14

Trends of AE event counts and energy counts of C40 concrete blocks and their respective percentages: (a) percentage of AE event counts to total counts; (b) percentage of AE energy counts to total counts; (c) trends in AE event counts and energy counts. E_s: elastic stage; Ne_s: nonlinear elastic stage; Ept_s: transfer to expansion pressure stage; F_s: fracturing stage.
