Composite Design and Analysis Software
Why use composites?
- Composites allow the construction of structures of almost limitless shapes. They can be molded into very complicated shapes that other materials would struggle to form.
- Composites are strong, lightweight and have a great strength to weight ratio.
- They have natural corrosion resistance, are non-conductive, non-magnetic and are radar transparent.
- Composites can have low thermal conductivity.
Composites are used in a wide variety of industries. From sporting goods to aircraft, composites can be the optimum choice for your project. We can show you how to best utilize composites in your design for creating models that get you faster to the manufacturable end product with still having high impact strength. Composites don’t yield, they are not brittle and they routinely perform in severe environments. Composites can be the material of choice for a vast array of projects and applications.
Femap supports composite analysis by providing many tools for modeling and postprocessing results on composite structures. For modeling, Femap provides the laminate editor and viewer, which allows you to define and modify plies of a laminate. With this laminate editor, you can immediately view the equivalent properties on the fly such as the equivalent properties of the overall laminate for stiffness and CTE. Support for both 2D and 3D composites with various failure theories is included. Also, global ply postprocessing can be performed to allow for viewing of results on continuous plies throughout the model.
NX Nastran is the ideal tool for analyzing composite structures. NX Nastran includes features to represent each ply individually within a two-dimensional element by using the PCOMP card. NX Nastran also includes a number of failure theories and can directly calculate both failure index and a strength ratio for each ply of the laminate for every element in the model. Sizing is easy once you know which direction is experiencing the lowest margins. The PCOMP card can simulate all types of composite structures, from solid laminates, foam cores and honeycomb core layups.
Fibersim software is a powerful add-in for NX, Pro/E, and Catia. It greatly simplifies the task of design, analysis, and manufacture of composite parts by giving engineers the tools to easily modify, update, and iterate on composite designs. This allows the engineer to work with combinations of material types, fiber orientations, stack-up orders, balance, symmetry, drop-offs, splices, and dart definitions. The add-in integrates this large set of attributes into the design by automatically creating ply-geometry, assessing ply-level producability, and providing excellent exchange of analysis and manufacturing data.
HyperSizer provides six steps to help design and optimize laminates simultaneously for strength, stability, and manufacturability. It begins by generating composite laminates, defining optimum layup areas and end-of-ply transition zones on the part surface, solving for ply count compatibility across the zones, and then sequencing the actual ply ordering while reducing weight and minimizing ply drops. Factors are provided for controlling which plies to drop, plies to maintain continuous across transitions, and the amount of interleaving. The last step provides convenient ways to perform final edits to the laminates and to export and import from Excel spreadsheets, FiberSIM, and CATIA.
