Applications of Supercomputing to Interdisciplinary Computational Mechanics

This research constituted an effort toward the development of unified computational methodologies, solution algorithms, and finite element modeling/analysis strategies for interdisciplinary flow-thermalstructural problems. The philosophy and rationale advocated in the study was 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 included: • Development of new time integration algorithms for transient problems

• Development of effective finite element based methodologies, which can be used in multi-disciplinary problems
• New physically correct contact models for penetration and impact problems
• Application of finite element methods in the manufacturing simulations
• Providing a paradigm for Virtual Manufacturing

The application areas included a wide range of engineering applications involving metal forming, casting, thermal degradation, and composite material processing. The overall efforts focused attention on providing new and effective approaches, for not only improving the existing applicability to supercomputing environments, but also toward providing an accurate understanding of the physics and mechanics relevant to multi-disciplinary engineering problems.
