Abstract
Electro-ceramic materials are widely used in the construction of power grids in China due to their good insulating properties. The high-strength porcelain casing of electric porcelain-type electrical equipment is the weak link in seismic action, and has high fracture susceptibility. In different loading rates, especially in the middle and high loading rates the mechanical properties of electric ceramic materials have large differences, clearing the differences in the mechanical properties of electric ceramic materials under different loading rates can provide a basis for the seismic design of electrical equipment. In this paper, from the quasi-static and dynamic response experimental research of electric ceramic materials, including experimental techniques, strain rate effect, etc., the mechanical response characteristics of electric ceramic materials under different strain rate loading are reviewed systematically; the dynamic constitutive model is elaborated; the dynamic constitutive model of electric ceramic materials considering the strain rate effect can be used as a reference for revealing the dynamic damage mechanism of electric ceramic materials under different strain rates.
