Abstract : Multiple temporal and spatial scale methods were developed and employed for the study of structural dynamics system in which the response is characterized by multiple-spatial and multiple-time scales. The following fundamental research topics were addressed: (1) development of multiple scale Reproducing Kernel Particle Methods, which can provide accurate mesh free interpolation functions and possess superior convergence rate for compressible flow-structure interaction problems; (2) incorporation of multiresolution analysis concepts into RKPM so that the response can be separated into multiple frequency/wave number bands for a better representation of the computed physics; (3) incorporation of (1) and (2) via a 2D pilot computer code; and (4) application of the multiple-scale computer code to study nonlinear compressible flow and large deformation structural phenomena.
