Computational Mechanics and Multi-Disciplinary Applications to High-Performance Supercomputing Environments

This project is concerned with the development of unified computational methodologies, solution algorithms, and finite element modeling/analysis strategies for rigid-flexible multi-body dynamics, contact-impact-penetration, electromagnetics, multi-disciplinary flow-thermal-structural problems, and micro/nano-scale effects in heat conduction. The philosophy and rationale of this work is based on employing a common numerical methodology for each of the individual disciplines in conjunction with common computational algorithms for applicability to supercomputing systems in solving large-scale engineering problems. Various research activities include: development of new time integration computational algorithms for transient/dynamic/contact/ impact/damage/penetration problems; development of effective finite element-based methodologies that can be used in multi-disciplinary problems; new physically correct contact models for penetration and impact problems; and application of finite element methods in manufacturing simulations to provide a paradigm for virtual manufacturing and the simulation of virtual experiment and virtual testing. The application areas include a wide range of engineering problems involving multi-physics and space/time domain decomposition with interface to graph partitioning techniques. The overall efforts focus attention on providing new and effective approaches for not only improving the existing capabilities for applicability to supercomputing environments, but also towards providing an accurate understanding of the physics and mechanics relevant to multi-disciplinary engineering problems.
