immersive FIBER
is an interface connecting MOLDFLOW and ABAQUS that helps you achieve best results in finite elements simulations of injection molded, short fibre reinforced components with anisotropic material properties.
Fiberorientation and distribution are obtained without additional effort during the mold filling analysis. These data are used by immersive FIBER to generate ABAQUS input files for structural and thermo-mechanical calculations.
immersive FIBER is developed since a decade and on the market since 1998. Extensive test series proof the capability of the chosen methods and the significant gain in accuracy.
This gain can be reached with negligible effort - so why not make use of it?
Material properties of short fiber reinforced plastics depending on fiber orientation
Features
- transfer of fiber orientation (averaged over each element) and distribution (degree of fiberorientation in the element, from random to unidirectional)
- automatic removal of special elements used in molding simulations (gates,..)
- automatic calculation of tranversal isotopic material constants depending on the degree of orientation. Micromechanical methods like Halpin-Tsai (mechanical) and Marom-Weinberg (thermal) are used to obtain these values from the isotropic properties of matrix and fiber.
- materials may be temperature dependent
- No User-Subroutines needed, thus simplifying daily use and pre/postprocessing
- bidirectional: node and element numbering changed by MOLDFLOW is recovered
- results from symmetric MODLFLOW runs are mirrored to obtain the correct behavior over thickness
- orientations and materials may be gathered in an arbitrary number of classes. By averaging adjacent layers their number over thickness may be reduced, both significantly reducing the size of the inputfile and the time spent for setting up data in ABAQUS.pre
- possible transformation to meshes made of quadrilateral elements. Splitting quadrilateral elements in triangles for Moldflow and subsequent automatic rejoining superseds providing different meshes
- higher order elements (quadratic tria or quad elements) are possible by request
