“…Comparing with (6), we observe that (24) is very similar to (6), except that there is more degrees of freedom in (24). Hence, in Section 4, we will use (6) to simplify the presentation of the coupling strategy.…”

“…Here, we summarize methods of direct time integration suitable for usage in dynamic FE computations [13]: explicit methods [2,3,5,[14][15][16][17][18][19][20][21][22][23][24][25][26][27][28][29][30][31], implicit methods [32][33][34][35][36][37][38], implicit-explicit methods [39][40][41], multi-time step and time sub-cycling methods [31,42,43], heterogeneous and asynchronous time integrators [44][45][46], variational time integrators [47,48], various local stepping approaches in time [49][50][51][52][53], time schemes for higher-order FEM and isogeometric analysis [2,54], and methods based on binary partitioning using a variable time step size…”

“…These constituents interact to form a collective system, herein referred to as coupled model . Such focus is relevant as many numerical models in civil and infrastructure engineering are indeed coupled models that are an amalgam of multiple constituents or systems of constituents; see, for instance, the published literature on soil–structure interaction (Provenzano, 2003; Qian and Zhang, 1993), fluid–structure interaction (Kutay and Aydilek, 2009; Caracoglia et al, 2009), human–structure interaction (Macdonald, 2009; Wang et al, 2011), and the broad field of substructuring (or subdomains), which essentially focuses on structure–structure interaction (Mahjoubi et al, 2009; Mahjoubi et al, 2011). While aiming to improve the predictive accuracy of such coupled simulation models, one obvious question arises: to achieve the greatest reduction in model uncertainty and bias, which constituent must be given the highest priority for further code development?…”
