Material cards and material data sheets – milestones for new development

We are surrounded by materials at all times and everywhere. From sports equipment to aircraft, materials play a significant role. Structural strength, durability or haptics – properties that define product safety and quality perception. In the automotive industry specifically, we can look back on many years of experience at ARRK Engineering.

As a capable partner, we support the development of components or subsystems from the material perspective; from material selection and static and dynamic material testing, right through to comprehensive identification of characteristics, and specification of CAE material cards used by us or our customers in structural CAE design. In addition, we help automotive manufacturers and their suppliers to comply with statutory directives in the field of material usage and material bans.

Our strengths

The strengths of our CoC Material range from material selection support, to evaluation of the material in the component. To assist product development from all material-related perspectives, we provide established expertise in the following competence areas:

Material data sheets (MDS) / material bans

Moreover we offer the OEMs and their suppliers a long standing expertise in the evaluation and compilation of material data sheets (MDS) for the development phase and in consideration of the materials and chemicals legal standards and requirements (REACh, EU end of life vehicles directive ELV .etc). The long-term experiences in a professional elaboration of databases and an established knowledge of the IMDS Platform enable an autonomous and complete project execution from the supplier management until the change management in the own system at the OEM.

  • Material datasheet assessment
  • Material datasheet creation
  • Life cycle assessment
  • Material reconciliation
  • Material restrictions

Material testing

To obtain sufficient information on existing material and evaluate its suitability for use in the development of a component, numerous tests are required. We execute these tests in accordance with international test standards based on ISO 17025 processes.

Material characterisation in CAE

Through close collaboration between our materials laboratory and the simulation department, we can offer our customers a comprehensive solution and adapt both the material model and the test programme to the needs of our customers. With this procedure, we achieve forecast-capable material cards, which can for example be used to predict crash behaviour via simulation.

  • Selection of a suitable material model in Nastran, Abaqus, LS-Dyna, PAM-Crash or Radioss
  • Modelling of elastoplastic behaviour and failure response according to triaxiality, strain rate and temperature
  • Characterisation of materials such as for example metals, plastics, CFRP, GFRP or foam
  • Characterisation of weld, screw, riveted and adhesive joints
  • Project coordination from test programme design to output of the finished material card
