Join the workshop sessions about short fiber reinforced plastics, continuous fiber reinforced plastics, additive manufacturing and automotive.
In the past 16 years, the team of e-Xstream engineering has been focusing its effort on the individual building blocks of the material modeling workflow. Accurate material models for short fiber reinforced plastics, SFRP*, have been developed – ranging from a simple elastic model to advanced temperature – strain rate – pressure dependent model for failure and fatigue behavior. While continuing to extend the range of material models, improving the CPU performance, robustness and easiness of Digimat became a major goal. As an example, speed and robustness has been significantly improved thanks to the Hybrid procedure. Furthermore, the introduction of Digimat-RP brought high accuracy with ease of use to the market for structural applications. This allowed the automotive industry to get the benefit of our multi-scale modeling strategy. The larger adoption of the automotive industry highlighted new challenge for Digimat, e.g. NVH, creep and virtual testing.
Adopting the best methodology that combines the building blocks of the material modeling workflow is sometimes challenging. The quality of the predictions does not only rely on the accuracy of the material models. It strongly depends on the quality of the experimental data, the post-processing methodology, the calibration and the input data of structural applications. During the last few years, e-Xstream extended its capability on the calibration of advanced materials law covering temperature, strain rate dependency, creep and DMA.
The workshop aims at:
In a continuous effort to enhance the Digimat platform capabilities, new methodology and modeling has been proposed to address Automotive and Aeronautics Industries needs as far Continuous Fiber Reinforced Polymer are concerned.
Traditionally, screening, characterization and even design is done by physical testing, but composites materials offer a so large choice of material combination so that such traditional approaches become inefficient at best.
As a response to that need, the latest capabilities of Digimat aim to accelerate the insertion of new CFRP for applications by reducing the total time from initial screening of materials to final, optimized and less conservative design.
During that workshop, we will take the opportunity to give an insight into the following Digimat new capabilities:
On top of this review, the objectives of that Workshop will be:
With a record growth seen in materials segment of the industry in 2019, Additive Manufacturing has now become an effective industrial production technique. While AM brings valuable opportunities to the industry (weight saving, customization, decreased time-to-market), it also comes with a series of challenges to meet high requirement applications. These challenges call for multiscale, AM-focus simulation techniques to optimize the design to print workflow and achieve ‘print right the first time’ capability.
During the workshop, we take the opportunity to illustrate how advanced simulation tools can be used to address the main challenges associated with Additive Manufacturing, such as the dimensional accuracy and the reliability of the mechanical properties of the final part. We will review the latest capabilities and improvements to the software (such as stress relaxation, enhanced post-processing, CPU performance and fibers-reinforced 3D printed materials) and also discuss how numerical simulation can further support the AM industry.
