Abstract
The thermal destruction of electrically heated metal wires is considered with respect to nominal end extra-employment (extra-loads). Few appropriate mathematical models are constructed and investigated thoroughly. It is shown that under-load regimes of heated wire operation provide its long-life functionality. The only realistic mechanism of wire crash is selfaccelerated evaporation of metal in previously thin zones. In the research both analytical and numeric techniques are used, as well as modern computer aided systems. Results obtained are interesting for electric equipment design and for educative purposes.
