FDTD Simulation of Electromagnetic Field, Heat, and Thermal Stress in a ZnO Element for Lightning Currents

Electromagnetic fields, heats, and von Mises stresses in a 37-mm-thick ZnO element have been computed with the FDTD method. The FDTD-computed von Mises stresses ignore shear stresses, but they agree well with those computed with the FEM that considers shear stresses. The FEM-computed maximum principal stress is almost the same as the FEM-computed von Mises stress for a current with a duration of 24 μs, but there is about a 30% difference between them for a current with a time to half peak of 100 μs. © 2025 Institute of Electrical Engineers of Japan and Wiley Periodicals LLC.

期刊介绍： IEEJ Transactions on Electrical and Electronic Engineering (hereinafter called TEEE ) publishes 6 times per year as an official journal of the Institute of Electrical Engineers of Japan (hereinafter "IEEJ"). This peer-reviewed journal contains original research papers and review articles on the most important and latest technological advances in core areas of Electrical and Electronic Engineering and in related disciplines. The journal also publishes short communications reporting on the results of the latest research activities TEEE ) aims to provide a new forum for IEEJ members in Japan as well as fellow researchers in Electrical and Electronic Engineering from around the world to exchange ideas and research findings.
