摘要

摘要研究发现，均质复合材料模型中的热释放是由平均电流强度和电压的焦耳-伦茨定律描述的。研究表明，尽管均质模型和实际复合材料中的电场电势很接近，但实际复合材料中的局部电场强度和局部电流通常与均质模型中的电场强度和局部电流有很大差异。

Justification of the Averaged Joule–Lenz Law for Composite Materials

Abstract

It has been found that heat release in a homogenized composite model is described by the Joule–Lenz law for the averaged current strength and voltage. It has been shown that the local electric field strength and the local electric current in a real composite are usually significantly different from those in the homogenized model despite the fact that the electric field potentials in the homogenized model and the real composite are close.
