Dynamic Substructuring is an engineering tool or technique to model and analyze the dynamics of mechanical structures separating their component level or substructures. Using the Dynamic Substructuring process, one can utilize the dynamic behavior of substructures separately and later calculate the assembled dynamics using geometric/dynamic compatibility conditions.

A nonlinear analysis is an analysis where a nonlinear relation holds between applied forces and displacements. Nonlinear effects in structures can originate from the geometric nonlinearity (large deformation), material nonlinearity (elasto-plastic), and boundary conditions (friction forces).

Hardware-in-the-Loop (HiL) simulation is a simulation technique used to develop and test complex real-time embedded systems. The simulation platform consists of mathematical modeling of the test and target hardware.
