초록
A 2-dimensional progressive failure analysis is conducted to predict the failure and strength of the unidirectional-fabric hybrid laminated composite joint under pin-loading. Eight-node laminated shell element is used for the finite element modeling. Post-failure stiffness is evaluated based on the complete unloading method combined with various failure criteria. Total of 52 specimens with 9 different geometries are tested to get the experimental strength and failure mode. The results show that the finite element analysis based on the combined Yamada-Sun and Tsai-Wu criteria predicts the strength and failure mode of the hybrid composite laminated joints with good accuracy.
