Numerical Simulation on AE Characteristics of Rock and Concrete Materials
Based on physical model of three-point-bending test, the AE characteristics of three-point-bending beams with different relative notch depth during the entire loading period was simulated by using RFPA3D(realistic failure process analysis) code. Simulation results show that the relative notch depth...

| description | Based on physical model of three-point-bending test, the AE characteristics of
three-point-bending beams with different relative notch depth during the entire loading period was
simulated by using RFPA3D(realistic failure process analysis) code. Simulation results show that the
relative notch depth affects the AE characteristics significantly. With increasing relative notch depth,
the occurrence of AE events decreases remarkably. The stress distribution figures, elastic modulus
photo and AE relative energy time-space distribution figures as well as an analysis on the failure
process are also provided. Based on the analysis of simulation results, it is concluded that the
heterogeneity of rock and concrete has great influence on the crack propagation path, which leads the
crack propagation path becoming curvilinear. |
