“…The potential of SBFEM in solving complicated engineering problems, unbounded domains, variation of material properties and loading, was remarkably recognized and considerably raise the application. Recently, several engineering problems have been efficiently solved and accurately investigated by employing the SBFEM including electrostatic problem (Liu and Lin, 2012), piezoelectric materials (Li et al, 2013a, Li et al, 2014, cyclically symmetric problem (He et al, 2013b), concentrated load on elastic medium (Vu and Deeks, 2014), two-dimensional linear multi-field media (Nguyen Van et al, 2017), etc. Based on such versatility, accuracy, and efficiency, the scaled boundary finite element method would be very suitable and become a better computationally efficient technique in investigating the mechanical behavior of infinite layered elastic medium in comparison with analytical technique (Rungamornrat et al, 2016, Tirapat et al, 2017, Tarntira, 2018 and the standard finite element method (Attia and Mahmoud, 2015).…”
