The influence of cross-section shape of the car roof rail on the quasi-dynamic buckling modes
MetadanePokaż pełny rekord
This paper presents the results of numerical analysis of the aluminium profiles subjected to dynamic, of different time duration impulse loading. The analysis includes the change in cross–section of the roof rail, ranging from the open ”C profile”, through closed ”Rectangular” to hybrid ”Tandem with brackets”. The main aim of this study is to model the dynamic response of the car roof rail to impulse loading, which may appear in case of collision.
