Simcenter 3D Composites
Simcenter 3D supports native composite material as well as other types of advanced materials like lattice structure or plastic material. It provides an efficient workbench for composites with a large set of tools to extract mid plane or modify the geometry on the fly. Simcenter 3D allows you to manage large assemblies with label management, including defining the dedi-cated physical properties of composite or fiber rein-forced plastic materials.
Powerful modeling tools
Simcenter 3D Laminate Composites software is a mod-ular simulation toolset for laminate composite struc-tures (continuous fiber). Easy-to-use ply and laminate definition tools enable you to quickly create finite element (FE) models in 2D and 3D representing your design, and helps you optimize and validate composite structures using your preferred solver. There is also a complete set of features to validate your draping simulation.
The environment provides capabilities to model highly nonlinear effects like progressive damage with dedi-cated meshing method for cohesive element generation.
Reduce laminate model creation time
Simcenter 3D Laminate Composites allows you to reduce laminate model creation time by choosing between zone-based modeling, ply-based modeling or a mixture of both approaches. Draping data like fiber orientation and material definition can also be imported form specific composite design tools. For instance, it’s possible to use the Fibersim™ portfolio, which is bi-directional, for ply exchange to communi-cate with composites designers. Plies can be imported directly from a Simcenter 3D .prt file, or via an HDF5 file. You can also exchange zone and laminate defini-tions via the zone interfaces.
Simcenter 3D composite simulation capabilities are used by many industries, although aerospace has always been a driver for this type of application thanks to its never-ending quest for reducing weight. These applications include:
Aerospace and defense
- Composites airplane frame – Stiffness, frame durability, nodal frequency
- Composite wings – Stiffness, skin buckling, modal frequency
- Satellite – Lightweight design
- Launch vehicles – Thermal stress, maneuver loads, payload bracket loads, lightweight design
- Aero engines fans – Rotating loads, distortion, composites
- Aero engines casing – Bearing loads, maneuver loads, lightweight design
- Manufacturing tools – Curing simulation
Unmanned aerial vehicle (UAV) primary flight structures, tie rods, compression struts, high-altitude telescope structures, cooling tubes, shuttle actuator mounts and turbine fan blades
Automotive and transportation
- Body – Roof crush, panel strength, stiffness, frame durability, lightweight design
- Chassis – Harshness loads, suspension deflections
- Manufacturing tools – Curing simulation
Drive shafts, suspension control arms, structural braces, crash structures and seat structures
- Ships, yacht, sport boats –Stiffness, deformation, strength, lightweight design
- Hulls – Skin rupture
- Bulkheads – Structural strength
- Boat hulls, decks and superstructures
Hand-held equipment made of composites – Drop simulation, plastic component stress
Easy-to-use ply and laminate definition tools in Simcenter 3D Laminate Composites enable you to quickly create finite element models of structures. Simcenter 3D Laminate Composites helps you create, optimize and validate composite structures using Simcenter Nastran® software, Simcenter Samcef, MSC Nastran, ANSYS, Abaqus or LS-DYNA as your solver. Laminate post reporting generates graphical and spreadsheet ply results from shell stress results and envelopes of ply stresses, strains and failure metrics on elements over multiple load cases.
- Keep your model up-to-date with the latest design using geometry associativity
- Interact with computer-aided design (CAD) based composites definitions from Fibersim, CATIA and others
- Use Simcenter standard materials, or create ply materials from the constituent fiber and matrix material properties, to simulate plies made of woven, unidirectional, randomly oriented short fibers and particulates and to represent cores
- Conveniently assign laminates and plies to your choice of geometry, meshes and/or elements
- Improve finite element modeling accuracy by accounting for distorted fiber orientations
- Postprocessing tools allow you to quickly identify critical plies and load cases using classical and user-defined failure theories and create reports
