Computational database technology for component mode synthesis
The present work show how object relational database management system technology can be used to support an finite element analysis process that includes component mode synthesis using the CraigBampton method for calculating reduced mass and stiffness matrices. A general object-oriented model for accessing matrix data independent of matrix representation is presented. The model is used to express the calculations of the reduced stiffness and mass matrices in a declarative query language and thereby letting the database decide how to execute the operations and manage the memory.
