Evaluation of the Damage Initiation of a Composite Thin-Walled Structure, on the Example of the ADUSTER Gyroplane Undercarriage

The subject of the research was a undercarriage leg of a gyroplane made of composite materials. The aim of the work was to assess the level of damage initiation of the composite gyroplane undercarriage. In the study, a structural capacity analysis was carried out, taking into account the phenomenon of damage initiation. Numerical calculations were conducted based on the finite element method in the ABAQUS® software. The issue was solved according to the Newton-Raphson algorithm.
