The proposed project aims to satisfy the urgent need for efficient design of large-scale thin shell structure in the vehicle, aeronautical/astronautically, and mechanical manufacture industries and to provide an efficient theoretical and computational method to simulation of dynamic nonlinear contact-impact procedures of thin shell structure. Computational efficiency is to be significantly increased by means of constructing the CAD model and novel element techniques, realizing the unified representation and seamless integration of CAD/CAE models in the field of nonlinear computation, and achieving GPU parallel computation in dynamic problems with large deformation via resolving key issues such as GPU mass data storage and parallel contact computations. The efficiency of iterative computation and optimization is also to be substantially increased by utilizing re-analysis to achieve rapid system response upon adjustment of design parameters. This project will result in a highly efficient CAD/CAE integrative algorithm with high levels of theoretical innovation, engineering practicality and a wide range of applicability. This algorithm will also take part in the construction of an efficient integrated platform for computation and will be validated through its application in vehicle design and manufacture. But above all, the algorithm will provide theoretical and methodological support for the innovative advancement of related industries.
