AASERT-92/Image Compression & Wavelet Generation

Abstract

The general research area was to develop shell finite elements for modeling tires. We started with a survey of the literature and the identification of several potential areas in which we could make some contributions. One was the extension of thick laminate theory to include hyper elastic effects. A second was the development of a suitable finite element discretization method for shells undergoing large deformations. The 'drilling' degrees of freedom were judged to be an important aspect of that development, and a separate study was begun on that. A third aspect was dynamic contact modeling. Mr. Maasha surveyed the literature and began to write some code including the drilling degrees of freedom which would have compared the existing formulations. Our intent was to identify which, if any, of the existing formulations for the drilling degrees of freedom we should use. Later, Mr. Warner began work on modeling contact as an intermittent slip/stick problem with frictions.
