Scalable Methods for Contact with Optimization

Executive Summary

We will develop scalable mathematical algorithms and high performance computing software to address limitations present in current state-of-the-art high-resolution contact mechanics analyses and engineering design, as encountered in programmatic missions and industry. The proposed research will substantially increase the scalability of both current and next generation design and contact analysis codes and will enhance stockpile stewardship and national security activities that are using these codes.
