Neural network prediction of aluminum-silicon carbide tensile strength from acoustic emission rise angle data [PDF]
FME Transactions, 2018 In this work, the ultimate strength of aluminum/silicon carbide (Al/SiC) composites was predicted by using acoustic emission (AE) parameters through artificial neural network (ANN) analysis. With this aim, a series of fourteen Al/SiC tensile samples were
