Abstract: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 tim… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
