Material Modeling – Current Practices and Future Challenges

Materials Modelling for Engineering Simulations – Current Practice and Future Challenges

21 - 22 March 2023, Helsinki, Finland

 

C​all for Papers / Workshops

Predictive numerical simulations of manufactured products require realistic and computationally efficient models of the physical behaviour of materials. In their daily practice, simulation engineers have to make several decisions to select the material model that is most adequate for the intended purpose (e.g., able to reproduce the physical reality of the problem at hand) given the available resources (e.g., time, computing power). Based on the scope and purpose of the simulation, aspects such as type of material, loading conditions, failure modes, strain-and stress magnitude, temperature range, and dynamic effects will determine what aspects the material behaviour need to be included in the model. The capacity to simulate the response of materials under various circumstances depends heavily on the availability of adequate experimental data for model calibration, which becomes particularly challenging for more advanced models, possibly accounting for coupled physical phenomena which occur at different length scales.

Examples of topics for this seminar can be:

  • Assessment of the adequacy of material models to the conditions being simulated.
  • Strategies for dealing with operating conditions that go beyond available material data.
  • Strategies for collecting testdata and to calibrate material models.
  • Methods to include effects of manufacturing processesinto account.
  • Novel material models – simulation nowadays is being deployed outside traditional. mechanical applications. E.g packaging material andbiomechanics.
  • Multiscale and multiphysics aspects of materials modelling.
  • Verification, Validation, and Uncertainty Quantification in materials modelling.

We are also open to suggestions for interactive workshops. For example how material testing and calibration of simulation models are planned and executed most efficiently. Anyone interested in contributing to that, let us know!

The conference will include keynotes, technical presentations, workshops and an exhibition.



From materials science to materials engineering: current practice and challenges

From the Stone Age to the Silicon Age and beyond, the history of civilisations has been shaped by the discovery and deployment of natural and man-made materials. The development of novel materials and more sustainable approaches to materials utilization are key pillars in any sensible strategy to face the challenges posed by climate change.

The introduction of novel materials and processes under tight constraints of cost, time-to-market, and quality imposes significant transformations to the established practice of engineering design and product development, such as higher requirements of physical fidelity and predictive capability for material models used in numerical simulations. The emergence of new applications as well as the increased availability of advanced theoretical concepts and computational power to model Multiscale and Multiphysics phenomena present both challenges and opportunities to incorporate materials in the design process.

Additive Manufacturing is an example of industrial application where the understanding of product properties is essentially dependent on the capacity to realistically simulate material behaviour at various length scales and phases. Advanced materials modelling open also new possibilities in areas with a long history such as welding, where modelling of liquid-solid interfaces at high temperatures provides additional control parameters for process optimization, and design of lightweight structures based on composites.

The emergence of design paradigms such as Integrated Computational Materials Engineering (ICME) and Hierarchical Materials Design (HMD), has provided a strong conceptual basis to demonstrate the feasibility of advanced materials modelling techniques to address problems in industrial applications. Interoperability between modelling software packages is a key prerequisite to enable the integration of computational tools operating at different length scales (i.e., from material structure to product performance), as evidenced by the recent efforts devoted by industry and research organisations to develop vendor-neutral standards for simulation data exchange such as VMAP. Robust approaches and tools to store and manage materials data will play an increasingly important role to secure the traceability, validity, and efficiency of numerical simulations, as well as to untap the potential of statistical techniques such as Machine Learning to extract useful insights from large sets of computed data.

The use of advanced material models in engineering design and analysis still faces considerable technical and organisational challenges related to computational as well as experimental aspects, for example:

  • Does the model adequately predict the material response for the given loading and environmental conditions?
  • How much and what type of data is required to parameterise the material model?
  • What is the computational overhead associated to the use of the material model?

This seminar provides an opportunity for delegates to learn how the many modelling issues related to this topic are addressed. It also provides a rare opportunity to network with peers who are faced with similar challenges and to exchange experiences within material modelling challenges and opportunities.

Expected contributions

  • Case studies illustrating how different types of materials have been analysed and assessed using simulation techniques (e.g., physics-based, data-driven, and hybrid approaches).
  • Examples showing the challenges faced by using existing material models to represent new and traditional materials (e.g., coupling between different length scales, Multiphysics, integration of material models in large-scale simulations).
  • Illustration of data management practices for materials modelling.
  • Presentation of methods for material models parameterization (calibration) and validation.
  • Research studies which introduce novel constitutive models.
