During this second three month phase of the seed project we have consolidated the phase 1 work on the Volterra formulation of linear quasistatic viscoelasticity problems, and three papers have now been submitted to research journals. Another paper is expected to be submitted before the summer. The visit of Dr. A.R. Johnson during March 1-8 was highly productive. During this time Drs. Johnson and Shaw implemented an adaptive solution procedure into Dr. Johnsons existing code for numerically simulating viscoelastic beam problems, while Dr. Johnson and Prof. Whiteman made progress on the direction the work should take toward simulating constitutively nonlinear viscoelastic response. During the visit of Dr. J. Illinger to BICOM on March 6 discussion took place concerning the extension of the seed project to a second year, Sept. 1998-Sept. 1999, in view of the undoubted success of the research and the collaboration between BICOM and ARL, NASA Langley.
