Abstract
This paper describes the mathematical simulation of an electric thermal explosion (ETE) in a gasless system placed in an annular layer of a conductive product. The influence of changes in the thermoelectric characteristics of a sample for the implementation of an ETE, thermal conditions, and ETE heat patterns is considered. Based on the results obtained, the previously established experimental result on the anomalous effect of the power of electric heating on the ETE parameters of a mixture of titanium and carbon black powders is explained.
