Multiscale Analysis Of Large Scale Nonlinear Structures and Materials

A typical structure (an airplane or a car) is of the order of magnitude of meters, while the size of the small features in the interconnect parts is of the order of millimeters. In order to determine the force redistribution between various structural components, fasteners, lugs and other interconnecting parts must be accurately modeled at a scale which is several orders of magnitude smaller than the entire structure. The useful life and cost of maintenance of the structure depends on the quality of modeling at each level and the ability of a reliable transfer of the appropriate information between various modeling levels.
