Finite element analysis of wrinkling membranes
Author(s): Miller, R. K.; Hedgepeth, J. M.; Weingarten, V. I.; Das, P.; Kahyai, S.
Abstract: The development of a nonlinear numerical algorithm for the analysis of stresses and displacements in partly wrinkled flat membranes, and its implementation on the SAP VII finite-element code are described. A comparison of ...
NASA Center: NASA (non Center Specific)
Publication Year: 1984
Added to NTRS: 2008-07-31
Accession Number: 84N23926; Document ID: 19840015858; Report Number: NAS 1.26:172325, NASA-CR-172325, USC-CE-83-05
Structures for remotely deployable precision antennas
Author(s): Hedgepeth, J. M.
Abstract: Future space missions such as the Earth Science Geostationary Platform (ESGP) will require highly accurate antennas with apertures that cannot be launched fully formed. The operational orbits are often inaccessible to manned ...
