The aim of the paper is to review different types of modern hybrid joints applied in aerospace. We focused on three particular cases: 1) spot welding - adhesive, 2) rivet-bonded and 3) clinch-bonded joints. The numerical models presented in the paper for these joints describe their complex behaviour under mechanical loading. The numerical calculations performed using ABAQUS code were compared to experimental results obtained by application of the Digital Image Correlation system (DIC) ARAMIS. The results investigated within the paper lead to the following major conclusions: - the strengthening of joints by application of adhesive significantly improve static strength, - the final failure of the joined structural system significantly depends on the surface adhesive area, - the stiffening effects of the hybrid joint lead to higher reliability and durability of the structural joints.

W pracy dokonano przeglądu różnych typów połączeń hybrydowych stosowanych w lotnictwie. Szczególną uwagę zwrócono na trzy typy połączeń: 1) zgrzewanie punktowe - klejenie, 2) nitowanie - klejenie, 3) klinczowanie - klejenie. Modele numeryczne złączy zawarte w pracy, ujawniają złożoną i trudną do przewidzenia reakcję tych złączy na obciążenia mechaniczne. Obliczenia numeryczne porównano z wynikami eksperymentalnymi otrzymanymi za pomocą bezdotykowego systemu pomiaru odkształcen i naprężeń (DIC) ARAMIS. Główne wnioski z prezentowanych badań: - zastosowanie kleju powoduje istotne zwiększenie wytrzymałości statycznej testowanych połączeń, - na końcowy efekt zniszczenia złącza hybrydowego znaczący wpływ ma powierzchnia złącza klejowego, - zwiększona sztywność złączy hybrydowych powoduje, że mają one większą niezawodność i trwałość jako połączenia konstrukcyjne.
