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.

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













  • development of new numerical methods and constitutive laws in the field of damage mechanics, applied in the composites engineering
  • stress analysis of composite and metallic structures, primarily in the aeronautics, as well as in the other areas of application
  • expertise and creation of technical reports in the area of aeronautical engineering and other fields of aeronautics
  • collaboration in FP7 and other international scientific projects in the field of composites aeronautical engineering and composite structures with particular aim at application of numerical methods
  • collaboration in engineering / scientific projects (such as national Technology Projects, national Scientific Projects, EUREKA projects etc.) in the fields of composites engineering and aeronautical engineering in general sense
  • consulting support in the field of aeronautical engineering















  • Workstations with 2 x 4 core processors
  • other supporting computational equipment (notebooks, printers, scanners, overhead projectors etc.)
