  • RPI SCOREC - Technical Reports
    This system fully integrates simulation into the design process by tying simulation attributes to the parametric design geometry and automating all of the simulation process Automation and reliability are obtained through the use of geometry based automatic mesh generation error estimation and mesh adaptivity The system allows a design engineer to quickly and easily validate the effect of design changes on the performance of the product A key to the

    the matrix are preferentially oriented close to the interface with the relatively rigid fillers this leading to a graded interfacial layer about each inclusion The composite elastic moduli are determined based on the properties and geometry of the interfacial graded layer as well as on the moduli of the filler and the matrix and the volume fraction of filler Conversion curves are constructed allowing for an equivalence to be established
