With increasing energy costs and stringent
emission targets aiming for 95 g/km CO2 emissions
for the year 2020, material efficient lightweight
design and alternative propulsion systems play an
important role in today’s vehicle research and development
activities. Furthermore the security of occupants is a core
demand on passenger vehicles. MATISSE addresses both,
electric and compressed natural gas (CNG) storage systems
and an extensive use of light fibre reinforced structures.
For the reliable application of fibre reinforced polymers (FRP)
in a vehicle structure the accurate prediction of the material
behaviour using the finite element method (FEM) is crucial. MATISSE
focuses on advancing the modelling, simulation and testing capabilities
for FRP structures under dynamic loading (crash impact safety).
Crash modelling tools used in the automotive industry currently do
not adequately address a number of issues specific to FRP structures under these load conditions:
Consideration of the load history - in particular with regards to
crack initiation and growth – on residual strength and stiffness
Non-linearity in the stress-strain behaviour for multi-axial loading
Anisotropy caused by fibre orientation
Behaviour under continuous in-plane crushing processes
