A Coupled Eulerian–Lagrangian Framework for Tracing Dynamic Response of Polymer-Based Composite Laminates Under Close-In and Near-Field Spherical Explosions

Polymer composites are lightweight materials with superior stiffness and elastic characteristics, making them well suited for aeronautical structures under complex loading. This study investigates the dynamic response of FRP composite plates subjected to close-in and near-field spherical blasts using a Coupled Eulerian...

Axial load and strain prediction of square FRP–concrete–steel double-skin tubular columns using machine learning and nonlinear finite element analysis

Feature importance analysis revealed that axial load (Pu) is primarily governed by FRP stiffness, steel yield strength, and concrete strength, whereas ultimate axial strain (εcu) is dominated by steel tube geometry and strength, confirming that axial load and strain are controlled by distinct governing mechanisms.
