Digimat-RP: The Leading Solution for Reinforced Plastic Parts Simulation!
Digimat-RP is a Solution of Digimat software that integrates the right Digimat Tools and features to design Reinforced Plastics
Lightweight engineering re-designs metal parts into fiber reinforced plastics produced by injection molding. For reinforced plastics manufacturing procedures influence the material microstructure.
The effect of local fiber orientation leads to a distribution of material properties over the part. This can drastically influence its final performance and must be taken into account in the design procedures.
Digimat-RP (“Reinforced Plastics”) provides engineers with a guided simulation workflow tool that aids in the setup and streamlines the process of accurate analysis of plastic parts in a robust, fast and easy manner. It bridges the gap between injection molding and nonlinear FEA of plastic parts.
Digimat-RP simulation solution for Reinforced Plastics allows in a user friendly way to
- Load finite element analyses of a broad range of different solvers
- Assign a micromechanical material model to a specific part
- Choose a robust & fast multi-scale simulation method for a coupled analysis
- Map local microstructure information onto the part
- Launch & monitor the coupled analysis
- Access the results of the multi-scale simulation
Digimat-RP combines all the Digimat modules into a unique user-friendly interface. By following a logical workflow, the user can easily access the most important features of these Digimat modules to run a coupled analysis in a straightforward way. We are delighted that e-Xstream developed such a user-friendly interface which increases our efficiency without affecting the accuracy of analysis.

Digimat-HC for Honeycomb composite sandwich panels simulation
Digimat-HC is a Solution of Digimat software that integrates the right Digimat Tools and features for the virtual design of honeycomb composite sandwich panels.
The performance of composite sandwich panels depends on the properties of the skin and the core. These are determined by the choice of the underlying microstructure. The core is sensitive to the structure of the constituting honeycomb. The composite skins feel the selected type of fibers and stacking of layers with different orientations. Design choices are typically investigated in bending and shear tests.
The virtual design of a composite sandwich panel requires an efficient multi-scale modeling strategy:
The virtual design of a composite sandwich panel requires a multi-scale modeling strategy to be able to map the effect of the microstructure onto the macroscopic performance of the panel. In a coupled analysis the full setup of the panel can be varied and the impact on the final performance under bending and shear investigated in an easy & efficient way.
Digimat-HC simulation solution for Honeycomb composites sandwich panels allows in a user friendly way to:
- Set up the structure of a composite sandwich panel
- Define the properties of the core (honeycomb & foam)
- Define the properties of the skins (UD, woven & chopped fibers)
- Investigate the panel design under different scenarios (3-/4-point-bending & shear)
- Flexibly access the results of the analysis (field plot & through-thickness path analysis)
Digimat-AM is a solution of Digimat Software that simulates the printing process and helps printer manufacturers and end-users to identify manufacturing issues. It also optimizes printing parameters for productivity and final part performance prior to printing the first part. The use of numerical simulation allows you to turn hundreds of trials and errors into a couple of clicks in Digimat-AM.
Digimat -AM empowers engineers with a process simulation solution that helps:
- Simulate the FFF, FDM, SLS and CFF processes of unfilled and reinforced materials
- Predict the as-printed part warpage, residual stresses and process-induced microstructure
- Analyze the coupled thermal-structural response of the process for unfilled and reinforced polymers
- Set up the right manufacturing parameters for high precision printing and further bridge the gap between printing process, material and part performances.
Built upon our partnerships among the AM ecosystem, the software workflow follows the real printing process intuitively, allowing non FEA experts to fully benefit from our software solution.

Digimat-VA: Your next innovative Solution for Virtual Allowables Computation!
Digimat Virtual Allowables is a Solution of Digimat software that integrates the right Digimat Tools and features to predict the behavior of composite coupons
Digimat-VA (“Virtual Allowables”) is an efficient solution that empowers engineers to virtually compare materials before going into the lengthy physical allowables. By generating virtual allowables, engineers can now start the component design in parallel to the physical allowable campaign.
Digimat-VA is a vertical solution developed to virtually predict the behavior of composite coupons (unnotched, open hole, filled hole). It allows engineers to screen, select and compute the allowables of composite materials in less time and at less cost.
NIAR has been researching on virtual allowables development for past few years and was excited to see some of the methodologies are implemented in Digimat-VA in a user-friendly manner. NIAR and e-Xstream partnership brings the knowledge of decades of material allowables development and simulations to produce great tools such as Digimat-VA.

Progressive failure lets you describe the progressive laminate stiffness degradation throughout time, as a result of applied loads. Progressive failure also provides the ultimate strength of structures even after failure initiation.
Laminate A-basis and B-basis
B-basis is the evaluation of the tenth percentile of a strength distribution with 95% level confidence. A-basis is the evaluation of the first percentile of a strength distribution with 95% level confidence.
