Abstract:
A three-tiered implementation of a viscoelastic material (VEM) database under development is described. Using low-level calls, searches for characterized VEM's may be conducted based on property constraints ( e.g., modulus and loss factor at certain temperature and frequency) and/or other criteria (e.g., available thicknesses, type, etc.). 1. A graphical front end program that runs on a Macintosh personal computer is being written. It will be dynamically linked to VEM characterization and testing programs for data sharing. 2. A stand-alone program for UNIX machines using X windows is being written. Reports will be in the forµi of tables and X-Y plots. A similar program to run under MS-DOS is also being developed concurrently. 3. A VEM database engine which may be compiled and run on any computer that supports ANSI FORTRAN 77 is described. The engine consists of FORTRAN callable subroutines that search a VEM database created by a librarian program using VEM characterization data files.
