Entwicklung einer ganzheitlichen Methode zur Bestimmung des dehnratenabhängigen Verhaltens faservers

Tobias Schmack develops experimental and numerical methods for determining the strain-rate-dependent behaviour of simple laminates up to structure-like components made of fibre-reinforced plastics. The author proves that the consideration of the strain-rate-dependent strength increase of CFRP in the dimensioning of components holds an additional and so far largely untapped lightweight construction potential. The results show a good agreement regarding the strength increase with increasing strain rates between test and simulation.
