Abstract
Lightning strike will have intertwined multi-physical effects on carbon fiber reinforced polymer. According to experiments and high-fidelity simulations in this study, distinctive positive and negative feedback is originally identified between the entangled lightning effects in composites damage driving. The intricate mesoscopic feedback mechanisms are groundbreakingly revealed through the anisotropic equivalent circuit. Positive feedback exists between ablation and mechanical effects, while thermal strain is counteracted by overpressure and ampere force effects. These feedback relationships are formed due to dissimilar action mechanisms and energy transformations, which dynamically change with time and location. They jointly cause complex non-uniform damage to composites.
期刊介绍:
The International Journal of Mechanical Sciences (IJMS) serves as a global platform for the publication and dissemination of original research that contributes to a deeper scientific understanding of the fundamental disciplines within mechanical, civil, and material engineering.
The primary focus of IJMS is to showcase innovative and ground-breaking work that utilizes analytical and computational modeling techniques, such as Finite Element Method (FEM), Boundary Element Method (BEM), and mesh-free methods, among others. These modeling methods are applied to diverse fields including rigid-body mechanics (e.g., dynamics, vibration, stability), structural mechanics, metal forming, advanced materials (e.g., metals, composites, cellular, smart) behavior and applications, impact mechanics, strain localization, and other nonlinear effects (e.g., large deflections, plasticity, fracture).
Additionally, IJMS covers the realms of fluid mechanics (both external and internal flows), tribology, thermodynamics, and materials processing. These subjects collectively form the core of the journal's content.
In summary, IJMS provides a prestigious platform for researchers to present their original contributions, shedding light on analytical and computational modeling methods in various areas of mechanical engineering, as well as exploring the behavior and application of advanced materials, fluid mechanics, thermodynamics, and materials processing.
