Modal Analysis of 3D Multi-axial Hybrid Composite with Experimental and Numerical Methods

Mechanical property analysis and experimental validation of composite honeycomb sandwich radome considering perforation and impact damage

“…The simulation analysis of composite corrugated plate crushing was carried out by Mou et al [2], and the nonlinear mapping relationship between specific energy absorption and material parameters was obtained based on orthogonal test data fitting. Song et al [3] used representative cells to characterize the multi-scale calculation process, simulated the modal behavior (natural frequency and modal shape) of composite materials by finite element method (FEM), and used a modal hammer with acceleration sensor to conduct experimental modal analysis of key vibration parameters. To evaluate the effective conductivity of graphite composites, Scocchi et al [4] conducted a set of simulations through experimental design aimed at identifying the microstructure details that are most important for the effective properties of these materials; Zhang et al [5] introduce a new virtual experimental method to estimate the effective transverse properties of fiber-reinforced composites (FRC) and analyze the effects of microscopic parameters (such as interphase strength and residual thermal stress) on the macroscopic properties of FRC.…”
