A research team led by Professor CUI Zhiwen from the School of Physics of Jilin University (JLU) has made significant progress in acoustic source localization technology for composite laminates.

Their innovative signal energy-based approach, published in the prestigious journal Mechanical Systems and Signal Processing, overcomes limitations of traditional methods that fail due to material anisotropy in composite structures.

The new algorithm eliminates angle-dependent constraints and reduces the number of unknown parameters in nonlinear equations, delivering improved accuracy and stability under challenging conditions.

This advancement enables more reliable structural health monitoring for composite materials, which is crucial for preventing catastrophic failures in aerospace and other applications, and creates new possibilities for damage detection.

The research was conducted by doctoral student MA Chenning under the guidance of the corresponding author, Professor CUI, and Professor Tribikram Kundu from the University of Arizona, with support from Jilin province and Chongqing research funds.
