Effects of Pore Distribution and Defect Parameters on Structural Vibration Characteristics of Foam Core Composites: Experimental and Finite Element Analysis

Key Points

• Structural vibration characteristics are significantly influenced by pore distribution and defect parameters in materials.
• Key evidence reveals that varying pore sizes can lead to up to a 25% difference in vibration frequency across samples.
• Finite element analysis was used alongside experimental observations to assess the impact of structural variations.
• Findings may encourage modifications in composite design to optimize performance under vibrational stress.
