This report documents a collection of papers on a family of uniform strain tetrahedral finite elements and their connection to different element types. Also included in the report are two papers which address the general problem of connecting dissimilar meshes in two and three dimensions. Much of the work presented here was motivated by the development of the tetrahedral element described in the report 'A Suitable Low-Order, Eight-Node Tetrahedral Finite Element For Solids,' by S. W. Key (ital et al.), SAND98-0756, March 1998. Two basic issues addressed by the papers are: (1) the performance of alternative tetrahedral elements with uniform. | Simpo PDF Merge and Split Unregistered Version - http www.simpopdf.com SANDIA REPORT SAND98-2709 Unlimited Release Printed December 1998 Ĩ r A Family of Uniform strain Tetrahedral Elements and a Method for Connecting Dissimilar Finite Element Meshes c.
