報告內(nèi)容： The increasing use of smart laminated composite structures in aerospace and high-performance engineering applications necessitates advanced numerical modeling strategies capable of accurately capturing their complex mechanical behavior. This study presents an innovative global-local modeling approach based on node-dependent kinematics (NDK) and the Carrera Unified Formulation (CUF) to enhance the simulation of wave propagation, structural health monitoring (SHM), and damage detection in composite panels with embedded piezoelectric sensors. By enabling kinematic refinement at the nodal level, this method ensures a detailed and precise description of stress fields, including transverse stresses—a crucial aspect often oversimplified in conventional models. The approach allows for the coexistence of high-fidelity layer-wise models in localized areas and efficient homogenized equivalent single-layer models elsewhere, optimizing computational cost while maintaining accuracy. Additionally, this framework effectively addresses multi-field coupled problems by incorporating electromechanical interactions between piezoelectric transducers and the host structure. This capability is essential for accurate simulations of SHM systems, where mechanical waves interact with embedded sensing elements to detect structural anomalies. The proposed methodology offers a robust and efficient tool for the analysis of active composite structures, contributing to the advancement of next-generation structural monitoring techniques and multiphysics modeling strategies in critical engineering applications. 報告人簡介： Enrico Zappino is an Associate Professor at the Politecnico di Torino, specializing in structural analysis and advanced modeling techniques.
