“…Tian et al [ 15 ] utilized piezoelectric ceramic sensors to detect the dynamic response of pipes under impact loads. In addition to these, researchers have also developed other kinds of effective methods, i.e., analytical solutions [ 16 , 17 ], finite element methods [ 18 , 19 ], conjugate gradient methods [ 20 , 21 ], basis function expansion methods [ 22 , 23 ], regularization methods [ 24 , 25 , 26 ], experimental detection methods [ 4 , 5 , 27 , 28 ], and artificial neural networks [ 29 ] have all been developed for impact recognition tasks.…”
