Abstract

Unfortunately, people can’t live in peace in this century: many wars and terrorist attacks have been wit¬nessed even within the last year. In the case of such attacks, both the people and the civil infrastructure is in danger. The modern age (infrastructure) provides electrical networks and communication networks for the citizens. Without electricity and/or communications (e.g. the internet), urban life is paralysed. Explosions create heat and shock waves and their effects can potentially damage the wall and cables of a building as changes in the material structure occur. In this article, the authors introduce a blast load effect testing meth¬od in an empirical way. The metal microstructure deformation level is measurable by changes in resistance, because resistance is a physical property which depends on the crystal structure of the metal.
