Abstract
model (FDM) for life prediction of unidirectional carbon fiber composites under variable block
loading conditions. First, the proposed modeling approach and its main calculation steps are
presented. Here, it is explained which model extensions were made in order to be able to reliably
perform fatigue analyses under variable block loading patterns. Second, results of finite
element simulations (which were carried out using the FDM) for multidirectional laminates
under different loading conditions were presented. Thereby, in addition to load sequences with
variable amplitudes, block loading patterns with combined tensile and compressive loads were
considered. Finally, the extended FDM was applied for damage prediction on a fuselage shell
of a blended wing body aircraft in order to demonstrate the model applicability to structural
use cases. All results presented in this study were critically examined for their plausibility.
In particular, the comparison of the simulations with experimental data for the block loading
investigations demonstrates the validity of the proposed FDM.

N2 - This contribution focuses on the application of a progressive fatigue damagemodel (FDM) for life prediction of unidirectional carbon fiber composites under variable blockloading conditions. First, the proposed modeling approach and its main calculation steps arepresented.

Second, results of finiteelement simulations (which were carried out using the FDM) for multidirectional laminatesunder different loading conditions were presented. Thereby, in addition to load sequences withvariable amplitudes, block loading patterns with combined tensile and compressive loads wereconsidered.
