This project aims to establish an innovative numerical framework for the computer simulation of systems of engineering structures subject to dynamic loadings. Scaled boundary polytope elements and an octree algorithm for mesh generation are proposed for adaptive nonlinear dynamic analysis at multiscales. It is anticipated that the numerical modelling and simulation will be performed automatically from the material meso-structures to achieve reliable predictions at minimum human and computational efforts. The intended outcome of this project is an innovative technology for numerical simulation and a rational predictive tool useful for the planning, design and management of engineering structures, and for the virtual testing of materials.
