Simulation of Low Velocity Impact on Composite Plates with Compressive Preload
The impact behaviour of fibre-reinforced composite materials is much more complex than it is for conventional metallic structures due to a number of different failure modes on the interlaminar and intralaminar level. In most of the ...

Untersuchungen zur Modellierung von Strukturen aus FKV unter Crashbelastung mit Hilfe von Mehrschalenmodellierungen
The numerical simulation of the crash front in composite structures is up to now still difficult. To improve the numerical results a so called ‘stacked shell’ model for laminated composites which is typically used for impact modelling ...

Characterization of Polyolefins for Design Under Impact: From True Stress/ Local Strain Measurements to the FE-Simulation with LS-DYNA Mat. SAMP-1
Optical strain measurement for the mechanical characterization of polymers, and in particular of polyolefins, is becoming a common practice to determine the parameters to be used in a finite element analysis of crash problems. This ...
