The present work is concerned with the modeling of progressive damage in fiber
reinforced polymer laminates and its implementation into a finite element code
as constitutive material law.
The objective is to predict damage evolution and material degradation due to
matrix dominated failure modes (matrix cracking).
In a previous work, a ply-level continuum damage model based on ply failure
mechanisms postulated by Puck has been presented.
This model predicts the evolution of the complete tensor of elasticity for the
damaged material and is able to capture the effects of stiffness recovery and
slanted cracking under transverse compression.
In the current work, this damage model is adapted for arbitrary loading paths
and implemented within the finite element method in order to analyze complex
structures and study their damage behavior including load redistribution due to
To demonstrate some key features and the application of the damage model in
structural analysis, it is applied in a single element analysis as well as in
the simulation of Open Hole Compression tests for which results are compared to
experimental data from the literature.
