Numerical and Experimental Research on Identifying a Delamination in Ballastless Slab Track. [PDF]
Materials (Basel), 2019 This paper aims to adopt the total focusing method (TFM) and wavenumber method for characterizing a delamination in ballastless slab track. Twelve dry point contact (DPC) transducers located at the upper surface of the slab track compose a linear array.
