The behaviour of materials is governed by the surrounding environment.The contact area between the material and the surrounding\nenvironment is the likely spot where different forms of degradation, particularly rust,may be generated.A rust prevention treatment,\nlike bluing, inhibitors, humidity control, coatings, and galvanization, will be necessary. The galvanization process aims to protect\nthe surface of the material by depositing a layer of metallic zinc by either hot-dip galvanizing or electroplating. In the hot-dip\ngalvanizing process, a metallic bond between steel and metallic zinc is obtained by immersing the steel in a zinc bath at a temperature\nof around 460?C. Although the hot-dip galvanizing procedure is recognized to be one of the most effective techniques to combat\ncorrosion, cracks can arise in the intermetallic ? layer. These cracks can affect the life of the coated material and decrease the lifetime\nservice of the entire structure. In the present paper the mechanical response of hot-dip galvanized steel submitted to mechanical\nloading condition is investigated. Experimental tests were performed and corroborative numerical and analytical methods were\nthen applied in order to describe both the mechanical behaviour and the processes of crack/cracks propagation in a bi material as\nzinc-coated material.
