The Laboratory, AeroDamageLab, was established in the 2009 at Faculty of Mechanical Engineering and Naval Architecture (FMENA), University of Zagreb, within the framework of the Technology Project TP-07/0120-30 “Numerical Modelling of Damage in Aeronautical Structures”. One of the objectives is to continue cooperation with flag carrier airline „Croatia Airlines“ in the development of technology aimed at determining foreign object damage (e.g. due to bird impact) in the composite, sandwich as well as metallic aeronautical structures.

The methodology is based on explicit integration methods used within finite element program Abaqus/Explicit, along with the corresponding failure criteria at impact on aluminium, sandwich or composite structures. Special attention was given to the modelling of impactor/bird (using EOS, ALE) in order to be able to compare numerical results with the available references.

The focus of current research activities is application of multiscale methodlogy in the damage modelling of fibre reinforced composite materials. The High Fidelity Generalized Method of Cells (HFGMC) has been used as a micromechanical model to model damage processes at the constituent level. Coupling between the micromechanical model and the finite element analysis has been achieved via Abaqus/Explicit user material subroutine VUMAT.

Furthermore, the Laboratory is the focal point for development of numerical methods in the mechanics of composites engineering.
