Project Title: 
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 and particle based methods such as SPH, MPS, DEM, Peridynamics and the like for modeling/analysis strategies for rigid-flexible multibody dynamics, contact-impact-penetration, electromagnetics, multi-disciplinary flow-thermal-structural problems and micro/nano-scale effects in heat conduction. Both continuum and granual material media that are heterogeneous are addressed. The philosophy and rationale 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. The simulations are conducted via integrating a variety of space and time integration algorithms in each subdomain of the overall domain.

Various research activities include:

  • Development of new time integration computational algorithms for transient/dynamic/contact/ impact/damage/penetration problems
  • Development of effective finite element and particle 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 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.
