Dynamic Characteristics of Damaged Hybrid Composite (Luffa-CNT): Theoretical and Experimental Verification

The time-dependent deflection characteristics of intact/damaged hybrid curved shell panels have been analyzed numerically under external loading and verified subsequently using experimentation. The effect of damage on structural integrity has been examined in order to identify practical implications.

The damaged hybrid structure (Luffa-CNT) has been modeled numerically in a computer code in MATLAB utilizing higher-order mid-plane kinematics based on a variational approach and finite element technique.

The concurrence behavior and model validity have been confirmed by associating the outcomes with the results available in the literature. This study also analyzed experimentally and numerically generated material properties from the DIGIMAT platform, further increasing the depth and precision of the analysis. Finally, several instances are provided to demonstrate the effect of damage, including several geometrical input parameters on the transient responses of the curved shell hybrid structure (HS).

The consequences obtained from this detailed approach are thoroughly investigated and addressed. The presence of damage weakens the structure’s stiffness by causing the laminate’s integrity to erode.
