“…The RPIM is a more complex version of the Point Interpolation Method (PIM) (Liu and Gu, 2001), using both the polynomial basis function (as the PIM) and an additional RBF, allowing the construction of stable and more robust interpolation shape functions. This meshless method has been used in many fields of application such as inelastic analysis of 2D solids (Dai et al ., 2006), 3D contact problems (Qian et al ., 2014), crack growth modelling in elastic solids (Nguyen et al ., 2014), homogenization techniques (Rodrigues et al ., 2018b), non-local constitutive damage models (Farahani et al ., 2016), the analysis for multi-group neutron-diffusion equation (Kim et al ., 2017) or the static (Belinha et al ., 2016; Belinha et al ., 2013) and dynamic (Phan-Dao, 2016; Pilafkan et al ., 2013; Phan-Dao et al ., 2016) analysis of composite plates and shells.…”
