Abstract
This research investigates the dynamic analysis of a shape-memory-alloy-reinforced laminated composite shell panel (SMARLCSP) with and without damage. The potential of SMA reinforcement against the internally defected composite structural panel has been explored by enhancing the parent structural stiffness and the corresponding dynamic responses. To ensure the accuracy of the proposed model, convergence studies, experimental tests, and numerical validations are performed. The theoretical and mathematical modeling of the study employs the higher-order shear deformation theory, offering improved accuracy for modeling the complex behavior of the SMARLCSP. The transient responses are determined using Newmark’s average acceleration steps via MATLAB computer code. The functional material effect has been included in this analysis via the marching technique to compute the numerical outcomes presented in detail. The study comprehensively evaluates geometric and SMA-relevant parameters for intact and damaged Laminated Composite Spherical Shell Panel (LCSSP) cases. The findings exhibit positive results, highlighting significant enhancements in structural stiffness and improved dynamic responses when SMA reinforcement is incorporated into the composite shell panel.
