Manufacturing A tool to set up composite material analysis J-Composites / Form Modeler

J-Composites Functions

A tool to set up composite material analysis with LS-DYNA

The J-Composites series consists of “Form Modeler”, a tool to set up a press forming analysis model, and “Fiber Mapper”, a tool to map the simulated fiber behavior from a resin flow on to a structural mesh .

Press forming simulation modeling tool: Form Modeler

J-Composites / Form Modeler provides three major functions: “Material DB” creates and manages material data, “Lay-up Modeler” creates a composite model, and “Lay-up Mapper” maps a fiber result to a structural model.

Based on material test results, J-Composites / Form Modeler automatically identifies the material parameters required for press forming simulation and uses them to create material models. The user-friendly interface enhances the efficiency of creating and managing laminate models.

Form Modeler Main Functionality

  • Material DB: Create and manage material data
    Material DB: Create and manage material data
    By using Material DB, material test data can be automatically converted into material property parameters for FEM press simulation. The resulting material model enables accurate estimation of the material behavior. With the help of the provided standard material database, users can start simulation right away.
  • Lay-up modeler: Define laminates
    Lay-up modeler: Define laminates
    By using Lay-up modeler, a press simulation model with a complex laminate construction (no. of plies, fiber angle for each ply) can be created in a few simple steps. Lay-up modeler auto-creates the various definitions needed for each ply in the laminate, including the conditions for contact with the tools, eliminating repetitive and cumbersome manual operations.
  • Lay-up Mapper: Map the resulting fiber direction
    Lay-up Mapper: Map the resulting fiber direction
    With Lay-up Mapper, the result of the press forming simulation can be used when preparing the subsequent structural analysis. Because fiber-direction governs the behavior of a composite material, a change in fiber direction during forming strongly influences the product’s mechanical properties. By mapping the post-forming fiber direction to a structural mesh, Lay-up Mapper enables structural analysis that accounts for the effects of forming.

Resin flow simulation model mapping tool: Fiber Mapper

J-Composites / Fiber Mapper provides an interface function which connects LS-DYNA and the forming simulation result. Connecting these enables structural simulation accounting for the forming simulation result for discontinuous fiber reinforced plastic (process chain simulation).

Fiber Mapper can map the forming simulation result on to the structural mesh and create a material model input, making it easy to create process-chain simulation models.

Fiber Mapper Main Functionality

  • Map the forming simulation result
    Map the forming simulation result
    Fiber Mapper appropriately maps the fiber orientation data obtained from a forming simulation on to a structural mesh. The mapping scope can be limited by part. Parallel processing is taken advantage of when possible to help map large models smoothly.
  • Ease complex and difficult composite material model creation
    Ease complex and difficult composite material model creation
