Case studies: Successful applications of 4a material cards

Case: Pedestrian Safety

● Low Speed Impact behavior

● Plenty of different plastic grades

● Temperature influence -35°C up to 80°C

Case: Composite hood

● Front hood

● Stiffness versus pedestrian safety

● Material card

● Composite layup with anisotropic material behavior

● Core material – Honeycomb different compression levels

Case: Sleeve

● Common isotropic modelling approach cannot capture local fracture

● Production process (fiber orientation) needs to be accounted for

Case: Packaging

● Droptest of plastic bottle

● Easy to use material card

● good prediction with new material card from 4a

Case: Mobile phone cover

● Cut out samples from real cover

● Conduct coupon material tests

● Check quality of provided material cards

● Generate new improved material card
