Tillförlitlig krockmodellering av fiberkompositer för lättviktsfordon (Compcrash 2)

Compcrash 2 involves joint work on crash behaviour of composite materials by two PhD students who have previously worked in two separate projects “Compcrash 1” and “FFI-Crash 2”. The main aim has been to extend the work from Tekn Lic to PhD exams, and to collaborate with the industrial partner Gestamp Hardtech on application of the model to industrial problems. This involves a closer interaction between experimental characterisation and modelling, consideration of the orthotropic properties in certain textile reinforced composites and demonstration of the capability to model experiments with demonstrator components. Simulation of coupon tests has been completed successfully, while more simulation of demonstrator tests are planned later 2018. The experimental studies of friction in crack surfaces, to be included in modelling, are delayed but are planned for spring-summer 2018. The planned pilot studies of strain rate effects in composites have been omitted, as more thorough studies of this issue are planned in a parallel PhD project in ICONIC and in the related FFI-project “FFI-Crash 2”.
