Simulation

Computer Aided Engineering (CAE) methods such as the Finite Element Method (FEM) provide nearly unlimited opportunities in engineering applications. By modelling the material and component properties in early conceptual stages of product development, great savings in time, material and money will be possible.

A plastic-compatible design as well as accurate simulation results require a very good knowledge of material behaviour. The behaviour of plastics is strongly influenced by the application conditions (loads, temperatures, moisture, etc.) and service life requirements of the corresponding components. Due to our experience and profound expertise in the field of polymer technology and material testing we are able to directly incorporate all important influencing factors (e.g. anisotropy,  load type and duration, temperature, environmental conditions) into appropriate simulation models. Therefore we are able to offer a broad range of simulation services including the determination of relevant material properties, calibration of corresponding material models as well as an experimental validation of simulation results.

We specialise in:

  • Plastics (thermoplastics, thermosets, elastomers)
  • Fibre-reinforced plastics
  • Hybrid material-composites (e.g. plastic/metal)
     

Special issues are:

  • Deformation and strength analysis
  • Simulation of long-term behavior and fatigue strength analysis
  • Stress-optimised design of plastic components
  • Influence of environmental conditions (temperature, moisture, etc.)
  • Design and computational analysis of mechanical and adhesive bonds
  • Notch stress analysis
  • Isotropic/anisotropic and linear/nonlinear material behaviour
  • Elasticity, plasticity, viscoelasticity, hyperelasticity
