DamageDict

Digital prediction of damage in components made of fiber-reinforced plastics

With DamageDict, Math2Market GmbH and the Institute of Composite Materials (IVW) in Kaiserslautern, Germany pursue the goal to model damage in fiber-reinforced plastic components on a microstructure level through simulation.

DamageDict - Predicting damage to components with fiber-reinforced plastics through simulation.

For this purpose, the project partners define material laws for modelling damage and failure behavior at fiber level. Based on reverse engineering, this methodology enables users in Research & Development to determine, for example, the properties of a matrix polymer from a tensile test carried out on the composite material through simulation as well as in the laboratory.

Along the DamageDict project, discover with Math2Market the possibilities of designing components made of fiber-reinforced plastics through simulation with GeoDict.

Project summary

Within the scope of the project, various work packages were carried out to enhance the modeling, simulation, and prediction of damage behavior in fiber-reinforced composite materials. The key objectives of the project included the development of damage models at the micro and meso levels, the integration of these models into a multiscale simulation methodology, and the validation of the developed workflows. Here is a summary of the key outcomes from the different work packages:

Work Package 1: Microstructural Modeling

  • In this work package, microstructural models were developed to understand the behavior of unidirectional composite materials at the micro level. These models allowed for the simulation of damage processes in these materials.

Work Package 2: Microscale Modeling

  • In this work package, material laws for fibers, matrix, and interface were developed to accurately describe damage processes at the micro level. Additionally, models for various types of defects, including waviness and resin-rich regions, were developed.

Work Package 3: Validation of Micro Models

  • The models developed in the previous work packages were validated by comparing them to experimental data. This involved tensile and compression tests as well as the modeling of defects.

Work Package 4: Development of Multiscale Methodology for Damage Prediction and Validation of Workflows

  • In this final work package, material models at the micro and meso levels were combined to develop a multiscale simulation methodology. The workflows for damage prediction and reverse engineering were validated.

In summary, the project successfully advanced the modeling and simulation of damage behavior in fiber-reinforced composite materials at the micro and meso levels. The developed methods and workflows enable a more precise prediction of damage progression and provide the foundation for improved material development in the industry. The achieved milestones demonstrate that the project's objectives were successfully met.
