Abstract
This study presents a detailed numerical analysis of composite beams enhanced with piezoelectric actuators, focusing on their mechanical performance under varying design parameters. Finite Element Analysis (FEA) using Abaqus software was employed to investigate the influence of fiber orientation angles (0° to 90°) and the number of layers (2 to 6) on the stress-strain behavior and bending resistance of the beams. The results demonstrate that optimal fiber orientation and appropriate layer configurations significantly enhance mechanical performance, with notable improvements in maximum stress capacity and strain energy absorption. The findings validate the potential of smart composite systems in advanced precision engineering applications and provide critical insights for optimizing their structural performance through parametric design adjustments.
This study also offers a comparative analysis with Classical Laminate Theory to identify deviations resulting from shear deformation and coupling effects. These results hold promise for applications in aerospace, robotics, and energy systems, where adaptability and structural resilience are essential.
